Marshallh of 64drive fame has released a demo for the N64 which as he put it in his own words "The first demo I've released. Running on a plain stock N64 with expansion pak."
The demo was released as a tribute to the MGC 2011.
Unfortunately this ting won't run on an emulator (laugh), you need the real deal to run this demo. Fortunately you emu owners a video is at least available.
But for backup owners, the actual demo is available below :-)
