I thought you might like to see how I layered the colors. The finished piece is bottom right.

Doodle No. 35 Rooftop Conversation

Remember Cat Planet? This is different planet that also has cats. Sure, you can only see one cat here, but there are more cats on the dark side of the planet. The scale in the right should give you a sense of how big everything is. 

I did something different with the colors on this one. I had a cognitive shift in how layering colors works. I layered colors on the opposite sides of the color wheel, and I’m telling you, it was pretty dicey there for a while because when you mix pink and green, you get brown. Half way through the coloring, I thought it was almost certainly past the point of no return, a total color failure,  At that moment, I took my Kepler dog for a walk to get away from it for a while. When I returned to this drawing, I decided it was salvageable. In the end, I got it right where I hoped it would be when I decided that mixing pink and green was a good idea.

Doodle No. 34 In one hole and out the other

This shows another version of the Poincaré model of hyperbolic space with microbes, space junk, aliens, and a few plants. 

Some are real. 

Some imagined. 

Some are totally unbelievable. 

I’ve worked in these colors before. 

I suspect I’ll use them again because they match the furniture.

Doodle No. 33 Tribert Makes Thymine

The design of this is based upon the Poincaré model of hyperbolic space. Ask a mathematician about it. It’s probably their favorite model of hyperbolic space. 

5.75” circle

A lot of people photograph their oakk in brings of flowers with real flowers. I don’t paint flowers. So I thought these Polyhedra seemed appropriate.

Doodle No. 32 Adam Explains How Holes Work

These weren’t the colors I thought I would get, but in the end I’m happy with how they turned out. It took a lot of layers of colored pencil to get there

. 

This piece is for someone who likes old wooden furniture and modern art.  It would look nice in a fancy guilded frame.

Doodle No. 31 Adam Makes an Atom

This is what happens when I let Melanie Schrader pick the colors.

Mike Ryan pointed out that the atom has three electrons, so it must be lithium. He cares for bipolar. Here is a detail of Adam and his lithium atom and the flash of the mica paint.

Doodle No. 30 Too Many Holes

In Doodle No. 24 Six Holes, I asked, “How many holes are too many?” The answer I was given was infinitely many. So then I spent the next several days trying to figure out how to draw infinitely many holes. The answer lied in the Poincare model of hyperbolic space. Here, I present “Too Many Holes.”

Doodle No. 29 Green Hole with Shrimp

If you ever visit a green hole, be sure to get a souvenir while you’re there. 

Someone challenged me to draw a black hole using a tiling other than the regular square one. That’s why there are triangles. Plankton and 2D RNA structures decorate the surface. The gold planet and most of the little dots shimmers in the light with mica paint.

Doodle No. 28 Moth Fractal

3.5” by 5.5”

Moths and a few copies of my dog, Kepler, inhabit a #fractal. The lizards and other doodles along the sides and top are very much in the style of Marty Kenney. 

The last several pieces I’ve done have a lot of coloring, a lot of pigment. This time I tried to use light colors with a lot of white, in part, to see if it would take less time to color, and it did! I’m sure I’ll go back to my saturated colors though. I love color, but this pink is nice for a change.

Some color schemes come easily to me. This was not one of them. I colored until I could color no more. Then I added 23.5 karat gold paint.

Doodle No. 20 Tribert’s Network

Tribert got a new antenna for his network in hopes of picking up owls. So far, so good.

Faber-Castell Polychromos colored pencils and Prismacolor black ink on Stonehenge paper

This piece is sold, but you can buy swag if you want!  I made stickers you can find in my Etsy shop here https://www.etsy.com/listing/713103849/doodle-sticker-collection

Also, I designed this piece specifically to be printed on shirts, stickers, mugs, etc., which you can find here. Www.gwenbeads.threadless.com I just ordered a shirt for myself in blue. It’s quite nice for twenty bucks. Sadly, the ladies fitted large is too big for me. So I have it to my sweetie. 


I’m not sure what this contraption does, but it obviously has a lot of functionality. 

Forgive the bit of reflection on the cat’s face. I have it temporarily sealed in plastic to keep it safe.

Pitchfork Bifurcation

Neenah acid free paper, 80 lb

5” by 7” image on 7” by 9” paper

I have a complicated relationship with yellow. I’m pretty sure it has something to do with the yellow and orange bedroom I had as a child. Everything was covered in a print of orange and yellow California poppies, and all of the furniture was painted yellow. Tying it altogether was a huge carpet in a perfect shade of yellow mustard. After the yellow experience, I had more than my fair share for years, and I didn’t like orange much either. I eventually brought orange back into my pallet a number of years ago after a friend successfully convinced me that bright orange is the color of happiness. Yet, that yellow carpet haunted me. With this piece I decided to put my biases aside and go full yellow mango on the background. 

Overall, this color palette is very 2019. Search for “color pallet 2019.” And you’ll find these colors. So if you don’t like them yet, you should reconsider.

The pitchfork bifurcation was the kind of thing I studied in my graduate abstract algebra course. The class had something to do with resolving “bad” points in the solution set for an equation by introducing another variable and changing your point of view. I didn’t really understand the symbolic representations and manipulations very well, but I could reproduce the kinds of pictures in the textbook in great detail. My professor seemed to think that showed enough understanding of the material for me to pass the class. It seems the biggest change between then and now is the cat. 

And yellow. 

And a lizard for Marty.

Doodle No. 14 Seahorses Fall in Love

Seahorses fall in love while visiting the second moon of Planet Coral. 

I tried to step away from the rainbows for this piece. The colors are contemporary, including Pantone’s 2019 Color of the Year, Live Coral. One tiny rainbow still snuck in, as they do.

Faber-Castell Polychromos colored pencils and Prismacolor markers on Borden & Riley 108 lb paper

I don’t know what you see, but mathematicians call the point in this surface a cusp. Sure, the algae and aliens make sense, and probably even the diatoms and other microbes, but I don’t know why the mean value theorem is there, or the challah. So don’t ask. 

I colored this piece with my new colored pencils. I purchased a complete set of Faber-Castell Polychromos colored pencils. I am now the proud owner of 120 colors in the metal tin. 

That’s almost 50 more colors than my current set of Prismacolors, which is a box of pencils I’ve had for over twenty years. Polychromos are all the rage now in the colored pencil community. People say they are among the best colored pencils you can buy. They’re harder than Prismacolors, which means fewer broken leads and sharper tips. That translates into finer details. Polychromos also have fewer colors with poor lightfast ratings than Prismacolors. So the purples will still be purple many years from now, as if that matters.

This piece is not for sale because it’s a birthday gift for a good friend.
