This thread gave me a good laugh. It's been a while, thanks. :')
Holes update: Over the weekend I spent like $120 on component parts to build an arcade controller/fightstick. I don't have the means/material to build a sturdy case though, so I may be looking forward to $120 worth of electronics screwed into a shoe box.
I probably should have thought this through more.
*edit: Also I have been half considering the logistics/feasibility of wiring up 2 cheap force-sensors into one of those creepy anime boob mousepads to make the best/worst/stupidest Divekick controller ever. I wish I could take credit for that idea, but that honor belongs to another GB duder from one of the Divekick forum threads.
Tested's Will Smith also uses Arduino, so you may find some satisfaction in his hole too.
Great suggestion. Although if I had to put my finger on Will's hole (okay, THAT one was unintentional), I'd say his is more focused on coffee brewing stuff. Granted, this is just extrapolated from all his chemex/electric kettle/metal filter/burr grinder/etc. videos on Tested.
And for the record, by the loose definition of "hole" I'm using (meaning a singular, focused obsession), Norm Chan's would be either expensive collectible art toys (http://www.tested.com/art/453615-show-and-tell-world-art-toys/) or taking pictures of people dressed as comic book characters (http://www.tested.com/search/?term=cosplay)
