Trying to remeber name of a demo
 

The demo was very good, it have some 3D raytracing balls with mandelbroth fractals rotating inside the balls.
Ring any bells?

No mandelbrot fractals rotating inside the balls but a cool demo anyway: Enigma by Phenomena maybe?

That's the one. Thank you very much !!!:)

Thanks, I never saw that one before. Found it in my collection with WHDLoad demos. You are right, it's a very good demo, especially the raytracer on the fractal is cool.:great

If you don't know Enigma / PHA i'd suggest to check others WHDLoad demos as WHDLoad team have fix lot of classic demos to run on A1200/A4000
