back in the 80s-90s if a system like raspberry pi was built, perhaps today
it had its own demo scene, like the amigas, ataris, spectrums etc. but
because rpi is a linux machine which is quite capable and generic it
doesnt. what a shame : but what if we could create our own demo scene for
this capable machine? draw only to the framebuffer and in lower resolutions
like 320x240 or 640x480 with 256 colors. it would be nice to see demos for
rpis :
fortunately there are some simple demos written for the framebuffer of
rpi. you can get them here:
https://github.com/drmad/rpi-framebuffer
or use git with this command to download the repo:
git clone https://github.com/drmad/rpi-framebuffer
to compile them just write:
make
if you want to preview the demos, watch a video of them here:

if you want to learn more about framebuffer graphics in rpi, read this
good blog, which has many tutors about the subject.

...and who knows... maybe in some years from now, see demos exclusive for
the rpi :
