While browsing around on the internet, I found a crazy promo video for the failed Nintendo 64 add-on, the 64DD.
The video features previews of Talent Maker, Polygon Maker, and Picture Maker...All of them look like they could be part of the same "game". Talent Maker looks like an early version of the Mii creation tool found on the Wii.
I also found a neat video showing what the 64DD startup sequence is like...and what happens if you don't put a disk in there.
