Alright, so here's the first effect I coded for the Dragon32 as a dragondos binary. Just a simple plasma to get the hang of things. Haven't had the time to test it on real hardware yet, but I'm assuming Xroar does a decent enough job with the emulation :)

Next goal is to make a few more effects and then write some kind of a music routine, as demos without sound are a bit boring.

Looks really nice, is this based on real time or bitmap based images and what is the impact on the CPU?

It's realtime, with double sine for both x and y. This version pretty much eats up all CPU time while staying 50fps, so combined with music the size would probably need to be reduced significantly.

So if one now should find a demo scene theme; what about then World of Dragon? :D Resonates good with the community efforts. Assume that the site admin wouldn't have anything against that?

I was going through some things this morning and ran across an old ad for the NDUG PD Library from 1992, that Stuart Beardwood used to run. There's a disk of demos listed with:

Amiga: Perhaps the most impressive demo you are likely to see on the Dragon!
Bubbles: Music + animation, with hypnotic screen display.
Plus: A huge collection of graphic and text screen routines.

I'm pretty sure the Amiga demo is a clone of the bouncing ball, done in PMODE4. I haven't found a VDK for this yet, but I know I've seen it before.

Not sure about this demo being available on a ".vdk", but here is a link to a YT video:

Impressive for a demo from 1986 and also based on that the Amiga 1000 was released 1985. So guess Martin who did this demo must seen it on a Amiga and spontaneous said "I can do that on my Dragon". Looks really nice!
