some of You might know the fantastic demo already, but maybe some - don't. http://pouet.net/prod.php?which=51782
(As You can see I finally managed to convince POUET admins to add ZX-81 section ).
Shit, I made a mistake in the author's name.

Sorry.
Btw, I will soon add here some more demos of him - for guys who don't know the progs yet - including the demo that proves ZX-81 has as huge resolution as Amiga500 (320*240).
Does anyone know what method was used for the hi-res graphics in this demo (the sources are missing from the website) - the site talks about needing hi-res hardware - is that the change to the 16K RAM pack, or the Memotech hi-res pack I wonder?
