Evodraw

Evodraw is an evolution simulation. True intelligent design. An actual god game. 

Design and draw anything you can imagine. Specify how much the muscles can move Press play and just wait one or two minutes before your creation is crawling, swimming or spastically flailing forward.

All your cute horses or indescribable abominations are controlled by a neural network (a Minimal Gated Unit if you're interested). And it learns by an evolution algorithm called evolution strategies. 

Is a small part of a bigger project I'm working on, where you can design an entire ecosystem with these creatures as building blocks. This is a tech demo for the creature editor of that bigger game. Follow me for updates.

Instructions:

Click-Drag the mouse on the background to move the camera.

Click-Drag from the edge of a body part to create a new limb at that point.

Right-Click drag upwards on a body part (you'll see a menu) to draw on only that body part.

Escape: Go back to creature-edit mode.
