Re:64kb demo 8 meg dload ? (Score 1)

all i can remember is they were Polish and the demo had full screen width lines in 100's of colours ( the specky was 8 colours + bright) and had a logo that had a kind of glassy effect in the middle of the screen.

That'll be Shock by ESI. Incredibly impressive at the time, but positively prehistoric compared to what's going on on the Spectrum these days... Gouraud shaded planets, Doom in multicolour anyone?
