Sorry for the flicking, there was a conflict with the screen recording application I couldn't resolve. Normally there is no flicker it's as smooth as silk.
RESDELET 2011 is an adaptation of a fun and harmless virus I wrote over 20 years ago. It hangs about in the background, and when you press the DELETE or BACKSPACE key, whatever letters you have on your screen start pouring down - with a bit of added mouse interactivity.
This version does *not* self-replicate - it is *not* a virus, just a bit of harmless fun.
