I guess I managed to obfuscate a lot of code. And with only the effect I was in 12 lines iirc. I had no inspiration for additional effects. At first I decided to call for music playing so that I intentionally reach 20 lines. But still I managed to obfuscrate the music init code too. So even if I am only at 14 lines I decided to stop here with this. Sorry, I never have motivation to fill those lines or those bytes left in size coding compos :P
It shows that much more can be done in 20 lines. And I was even too lazy to improve! O0

Goodnight..
p.s. Music by the hardliner btw.
p.p.s. I could obfuscrate more but it started being too slow. E.g. I made a test where I removed X, Y loops, inserted a For i=0 to 320*240-1 loop, and in all the big line with maths, I changed X with ((i mod 320) - 160) and Y with ((i \ 320) - 120). Crazy!!! But I decided to not put this here because it made the code even more slow and I already had more than enough lines anyways..
p.p.p.s. External files are allowed eh? Like fmod.dll and a music. Or not? I've seen somewhere that they are allowed..
p.p.p.p.s. And it still impresses me that by using FPU in such a crazy way with so many calcs per pixel (at least for small resolutions) can still have an ok speed. Not the way I knew to optimize things in quickbasic ::)
Really like this one! The math behind that sphere completely mystifies me ???
Nice going with two great effects in one :)
In 20 lines that would be slick, 14 lines for this is extraordinary O0 My favourite so far, speed is ok too :)
Wow, that's really cool :o
Been away for 2 days and you guys make some amazing stuff. Great jobs and proggies guys!!!!
Thanks, thanks! Now I am thinking about my second entry. Something diferrent this time..
That is purely awesome, nice one Optimus.
Wow, thats amazing to have both effects in such few lines
That's awesome for 14 lines!
