Nice to see something new coming out of my work on the eink algorithmic art scripting thread. Using "dd" as a blitter to draw on the framebuffer device is classic.
Other people have contributed scripts to the "algorithmic art" thread too, and PoP even converted his "3D" script to a C program later.
Doing this stuff in a script is more just for fun, to show that it CAN be done even with the most primitive of tools. That alone makes it really cool!
Thanks for sharing.
