Hi there !
Still working on my Atari St demoblog DEMOCYCLOPEDIA at https://democyclopedia.wordpress.com/
I'm starting to lack ideas about uncovered demos effects so please if you want to help, have a look at https://democyclopedia.wordpress.com/2015/10/25/liste-des-effets/ and tell me what is missing !
May the Fuji be with you :)
