Perhaps not a hoax but the floating nuclear power purportedly slated for construction by Russia couldn't look more retro. From TOD:
According to Bruce McCall, "all meat looks like South America", and so I can't but notice that these minimalist plans look much like the retro stylings of Mr. McCall, a cartoonist for The New Yorker and before that, National Lampoon.
Phila remains a fan of the original cartoon work that I believe McCall derives much of his inspiration from.
