One shot: Petri Purho's fractally fitted invaders

More curious developments in our latest Purho edition of What's He Building In There (which I suppose really should be its own category), as the Crayon Physics creator extends the generative aspects of his last character prototype even further with these mathematically created and arranged pixel Invaders.

As a bonus double shot, a look at a tiny fraction of the 32,768 unique invaders that can be created in a 5x5 grid, courtesy Jared 'Levitated' Tarbell, original author of the fractal invader code that Purho's prototype is loosely based upon. [all via Petri himself]
