I love looking at Signs of the Times (signage magazine) just to remind myself how lawless the 90s design landscape was
They've got a bunch from that peak of maximum-themed entertainment in the late 1990s. Luxor casino floor & Mermaids façade in Vegas, Port Discovery at Tokyo DisneySea, and one of those super-extravagant neon movie 'decoplexes' in Nashville
1940s-50s retro-futurism with the Cool Ship logo (love that 'melting coke comet') & Rocket Intergalactic Diner (can't find any info), a Factory Pomo kiosk at Dave & Busters, and Portillo's Hotdogs in the 'Boomer Diner Revival' style.
Examples of the Cyber Corporate style; including a giant glowing brain of Intel, rippling Pepsi supergraphic, and a strange Sony computer-clump cloud
