I'm surprised no one thought of rickrolls yet :P
Believe me, I thought of them and decided that I'd wait for sound. :P

Even one sync'd with another calculator for sound (bet you can't guess what that is ;)).

kindermoumoute, you got the uncompressed version that I uploaded first. Redownload the video file.

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

So it turns out that when super converts a video to .jpg's, it doesn't change the frame rate to what you want. So here is a video running at 29 fps. I couldn't think of anything cooler, so this is what you get.

Edit:
    Again, this looks better on wabbit than in the screenshot.

Oops, I accidentally left off the last 62 frames of the video. (fourvid.exe <source folder> <output file> <number of frames>). So here is the full video in 12 shades of gray.

Edit:
    Has anyone tried this on a real calculator?

I imagine dithering would help.  It might also be interesting to consider adjusting the LCD contrast.  And now I'm wondering if there would be enough CPU time to do any more sophisticated decompression.

Also, the Old Spice example looks like it had some serious MPEG and/or JPEG compression artifacts to begin with.  Or maybe the conversion is making the existing artifacts a lot worse.
