The Opal controller
By reading this guy’s site, one gets the feeling that he was the original designer of the C-Thru controller. And it looks as if he and C-Thru had a falling-out. So now he’s making his own version. It appears to be the same key layout as the C-Thru. No prices are mentioned. (Not likely to be a bargain.)
I only found out about this because an Opal owner put his hamster in a plastic ball and let the little bugger roll around on his Opal controller. And put it on Youtube. (I really do wish the “Web 2.0 Revolution” would allow us to tag Youtube videos for stupidity.)
