somewhat ontopic news: today was probably the first demoparty ever with not one, but TWO (completely independent) Haskell demos! :)

Assembly, because you have to be deluded to work on the Mega Drive in C. Seriously, compilers for it are just plain horrible, and also all the nifty software rendered stuff needs very carefully tuned instructions to not waste cycles (on the flipside, the stuff that involves hardware abuse is usually very light on the 68000, so there's that I guess).

I haven't yet tried making demos on other platforms so I don't know what I'd use there =P (but if it's an old enough system then it's likely I'll resort back to assembly again for the above reason)

Assembler mostly on Atari/Archimedes (long time no see btw), some precalcs in basic or c.

I was surprised to learn and, after what you just said, I'm now even more surprised to know that pier solar was mainly coded in C !

C#/GLSL (I use OpenTK as an OpenGL wrapper in .NET)

I used to code C++, but C# has rotted my brain like a month-old banana. Last time I coded asm in anger was on my pentium-100.
