I'd long thought of the various colored data cards as an influence in the creation of PCMCIA and CardBus devices for laptops. But today I've found a much more direct influence on the design of real technology. I fell down this rabbit hole thanks to the newly released Saurian Brandy glasses set. I figured the originals had to have been some off the shelf glassware. I wasn't successful at finding that but did land on the old reused props thread here. Have a look at Page 17 https://www.trekbbs.com/threads/props-re-used.81174/page-17 Compare the shape of the cards to a Seagate Free Agent GO external hard drive. https://pisces.bbystatic.com/image2/BestBuy_US/images/products/8293/8293982_ra.jpg Ever since I bought a 120 gig one of those drives some years back, I'd wondered why the housing is much wider than it needs to be, with the round edge and that bulky slope. Now I know. It's designer is a Trekkie! So am I, I read through the entire 26 page thread, just to see if the brandy glasses were mentioned.
