20 years ago Sanity released the Interference dentro on the Amiga and blew pretty much everyone away. It had a fantastic combination of excellent graphics, a superb soundtrack by Virgill and some very technically advanced coding (and cheating!). It’s little wonder it’s rated so highly in the Amiga demoscene.
Personally I find it fascinating how many old sceners are using the browser as a means to express themselves creatively these days, and having a lot of fun while doing it. Sites like We Are Back now hold upwards of 240 HTML5 demos and is constantly growing.
So kick it back old-skool for a moment and view Interference Recoded. Joerg recommends Chrome but it ran fine in Firefox 25+ for me, and even mostly runs in IE11 other than one small part.
