I wish someone could get a hold of the 8mm film and do a scan of it, even if you have the LD it's reportedly very prone to laser rot.
The entirety of the 2 films were part of the Little Boy exhibit at the Japan Society back in 2005, but they were only running a digitized file (of course). They did have a bunch of cels from it on display, though, which looked awesome.

A pity that 8mm is the highest resolution it will ever exist at (since I seriously doubt they kept all the cels and backgrounds, and even if they did many would likely be stuck together), and even the 8mm source will possibly never be seen again...
