Revision is a non-profit event; however, that does not make us non-cost. Do you want to help us in realising one of the biggest participatory programming art events? Then we'd be excited to have you!

An animated loop basd on the games of the ZX Spectrum 8 bit micro from the 1980s
This was made in photoshop and Blender and just a fun little tribute to my all time favourite home computer

New #demoscene platform just dropped?!
✨ New article ✨
Are we at the start of a new era?
Chrome 140 introduced CSS Typed Arithmetic. It might seem like a minor change, but I believe it's huge as it opens the door to countless new possibilities and a whole new era of Computational CSS.
What do you think?

Happy birthday to the MOS 6502! It was 50 years ago today that people were able to buy their first samples of the chip from a jar in a hotel room at WESCON.
Here's my oldest 6502 from the 52nd week of 1975. Still works perfectly!
