do you remember this?
I worked again on it and moved most of the work on the gpu.

simply press 'c' to create a new tower, write down that calculation time, press 'm', press 'c' again, and so on.
Would be really cool. Btw, this is optimized for DualCore Cpus but it works also on single cores, and please close alls background programs to get correct numbers.
Oh and you need a graphic card with shadermodel3.0 support (Geforce6, Radeon X1000 and up).
A small screenshot to make you wet:

I forgot to mention you need the latest directx dlls (november2008?), you can find it somewhere on microsoft.com.
