Two entirely different, but totally creative things that would probably never have seen the light of day if it weren’t for the Internet.
Back to the Future: The Enchantment Under the Sea Dance Revisited wherein the parallel 15 minutes of BTTF and BTTF II are edited in together so you can see how well they match up. They match so well, it’s uncanny. You’d swear they were filmed together.
Starship Dimensions where you can compare scale renderings of space vessels from across science fiction. Everything from a TIE Fighter through to Larry Niven’s Ringworld. Explore and enjoy!
