Britain's Keep Calm and Carry On posters are one of the oldest active memes. The originals are from the flippin' 1930s. Now comes the 1980s sci fi movie geek version! Watch Tron and Carry On.
Which you should. The seminal CGI film starring Bruce Boxleitner, Peter Jurasik, Jeff Bridges, Cindy Morgan and David Warner. Try to name one other film which crosses over cast from Star Trek: TNG, Babylon 5, Time Bandits and The Big Lebowski. I dare you!
I have a variant on this one with a fixed blue gradient background that I like. That's one is listeed specifically as a Watch Tron Phone Case.
But this version is a clear background and you can get it on any color you want.
