I kinda wanted to post this in the Starfox thread the other day, but it fits here too.
Gamevideos and Points TV had an interview with Dylan Cuthbert over in Japan. This man is apparently the mastermind behind the Super FX chip in the SNES, and it all started with his Gameboy game X. It was a 3D game on the original Gameboy.
Site with the interview here. It includes footage of the X game and some Starfox stuff.
It's pretty interesting how they talk about the history of it, and how gameplay elements from the scrapped 'Starfox 2' made it into following Starfox games. For example, the Strategy elements used in Starfox Command were all going to be part of Starfox 2 way back in the day.
