For those of you that like to show off with a big, flashy belt buckles, take a look at this DIY gaming-themed one--one that you can actually play. It will certainly grab people's attention, but perhaps not for all the right reasons.
Instructables user cunning_fellow built a funky brass belt buckle that doubles as a playable handheld-style game console.,. His buckle uses an LCD screen wired up to a circuit board and battery that's fitted neatly into an etched brass case. It can also play Rock Blaster, an asteroid-shooting game.
The LCD has a resolution of only 320 by 240 pixels, so it takes some clever coding and tweaking to avoid screen tearing. If you make this yourself, you'll have to also write some code to get the controller buttons to work.
Cunning_fellow plans to improve the buckle by adding audio support--just as soon as he find a speaker he likes, anyway. He also wants to add more games, such as a puzzle game and platform shooter.
Even with all these tweaks though, the belt sadly serves little purpose than to attract plenty of unwanted attention and leave you in some awkward social situations.
Um, I'll leave the rest to your imagination...
