The human mouth is kind of a bastard. Animating it frame-by-frame requires a patience that I just don’t have. Blender has shape keys that can help you mold lips into different configurations for each sound, but you still have to set keyframes to match up with a particular word at each and every frame.
Or you can be lazy. Like me.

Getting coordinates to scale properly to Blender units has been extremely frustrating for me since I started attempting more 3D maps. So, finally, in a fit of rage this weekend, I wrote a function to do it for me.
It scales the latitude and longitude down along the Z (height) and X (width) axes, taking into account the size of a base map oriented along those axes. In my version, it places a sphere at each coordinate set, but that can be easily changed to other objects.

After a long vacation, a wedding, a bad flu, and a whole mess of planes, trains, and automobiles, I’m back to talk about textures. I love playing with transparency in scenes, but scripting transclucency is a bit unusual in Processing. The normal Processing canvas doesn’t support an alpha channel, so it requires something called PGraphics().

Scenes with custom textures always seem to turn out better for me, but they’re hellish to make. I’ve spent hours in GIMP hand-drawing patterns, carefully testing out layers to get effects. It’s a hassle.
However, I’m learning to automate more of that sort of thing with Processing. What’s really nice about that is you can get a texture that changes subtly every time you run the script if you use the Random function to assign coordinates, weights, and transparency values.

Sometimes I get embarrassingly excited about being able to do things in Python that I will probably never need to do again. This is one of those times.
I had a mesh—a plane that I had turned into an a spiral walk-way. And I had the thought, this thing can’t have walls. Eventually I want the walk-way to be the center of a large arena that’s coated in fog. And the only way you’d really be able to see that it’s a spiral is if it’s semi-transparent and lined in lights.
