Electronic Images released one of the most hilarious Atari ST demos I have ever seen. I did try and record a video but my emulator missed some graphics and also the sine scroller (which is beautiful) was jerking like it had a nervous twitch. So I burned the image to a floppy disk and it was perfect - because nothing beats the real hardware!!
Download this utterly stupid demo from AtariMania then turn up the volume and enjoy the show.
