24-bit

I want to see a single image with all the 24bit (16.7m) colours in it. I'm asking in /prog/ because I'm not sure such an image exists on the Internet and probably the only hope is for someone to write a program to generate it. Thanks.

Thanks >>3, funnily enough I came across that same after posting here. It's my understanding that this is what you'd get through outputting colour "0" to colour "16777215", those nasty 256 colour blocks. Any way of arranging this in to more of a spectrum?
