I just found a screenshot on my computer that reminded me of something I saw a long time ago. I thought reposting would be a good idea since a lot of people probably missed it when it was first popular. These are two demos of sound and graphics, which are pretty amazing to see. DirectX 8 is required to run these.
Now here's the fun part, these are tiny tiny little files. 64kb to be exact.
The website for this is located here:
These are the two files in question.

These are .exe files, but they are not harmful in anyway. No viruses, no spyware, just the program.
The first one here was released a while ago (winter of 2000). This is certinly the better of the two. It's about 16 minutes long and is just about the most amazing thing you'll ever see. I found the soundtrack on this to be very good as well (you can download it from their site). This is a screenshot I took with my own computer a year and a half ago.
The second one, .poemtoahorse, was made around April of this year. It's shorter and not as impressive, but it mainly showcases new shapes and graphics they were able to produce.
Some fun facts: These demos use a compression rate of 30,000 to 1. Your computer is really producing 1.9GB worth of data. These are both definitly worth a look if you haven't seen them before.
