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.

By the way, unless you have a 4096×4096 capable screen and video card, you cannot view it all in screen at once. This means even though you have a palette of 16777216 colours, you can only see 786432 colours in 1024×768 resolution.
