T-G-G-F: Resonating Clear Speakers
One of the largest boards featured on this list, the Tech - Gadget - Geek - Future says it all. And really, there isn't much you won't find on this board. We got our steampunk and hipster categories covered; a plethora of vaguely futuristic items that may or may not become sentient; LEGO (because it never gets old); and everything in between. I even spied the laptop case my day job boss uses. My personal favourite however are the resonating clear speakers because they look fantastic.
