Bright boys looking to pimp their rides, apparently.
Eesh. Now, even conventional “spinners” remind me of nothing so much of eight-year-olds making their bikes all “ass-kicky and cool” by the addition of baseball cards through the spokes – but I’ve got to admit, that is some damned fine mechanical scanning, even if the application is a little misguided.
I’ve been wanting to make a MS display for a while now – but I’ll feel lame if it isn’t multicoloured. 
I guess setting the whole thing in nice heavy rims driven by a couple hundred horses makes the whole stability thing a lot easier to engineer, anyway.
But dammit, mechanical scanning is the rightful domain of geeks and hobbyists. It is definitely not supposed to be associated with “bling.” That’s just wrong.
