Wow, Kelsey really does great work!!! (Impressive!)
Christian, What good could a spinner spinning forever do for you? I could see how this would be good for a trackball (for like Bowl-A-Rama esqe games), but how would this be good for any realistic purpose?
Just thaught I would add...
"No not advertising, just telling you FACT." can be found in the SAME post as "be able to stop on the dime, be easy to switch directions, have an "adjustable" shaft, have superior mouse tracking accuracy, the Tornado has these all." (that last part sounds fresh out of an add!)
I thaught that was odd...
PS: I don't have the cash at the moment

It looks like I may have to sell some stuff.
So instead I am really getting serious about building spinners! I can see how it would be a SWEET job! I am working on ~ my 6th hack spinner, I haven't had any PERFECT results yet, but I am getting close; my latest uses bearings I actually got ordered instead of ripping them out of a HD

I have some soldering to attach push buttons- the mouse buttons, but then I am done! Soon I hope to get a decent website up.
