VERA Demo Screen written in assembly

I have been playing with the VERA chip in assembly, and have come up with a cheeky little demo screen that is reminiscent of some 80s demos I can remember as a kid. No music or fancy interactive stuff, but some of you might find it amusing.

Warning: As a GP I feel I ought to point out this demo contains flashing / strobing effects!

Thanks to the excellent tutorials of SlithyMatt - Commander X16™ Community, especially the latest one demystifying the VERA chip. I have used a lot of his code from the latest tutorial to create this demo.

Even more, slightly, nicer effect ?
