see ANY sonique visual (or most winamp visuals) to note that it is VERY possible to do fast per pixel operations using the gdi or directdraw.

EDIT: btw ALL sonique visials MUST end up as 32 bit images, so most are developed using 32bit depth. adavanced visual studio (winamp vis plugin), runs all its stuff in 32bit color as well. though you should stick to 640x480 and less resolutions.

Cool. Are they open source? I haven''t found the code yet.
