If by chance you're looking for yet another LED-heavy DIY project to tackle, you may want to take a gander at this so-called persistence-of-vision LED sphere, which will let you pump out some super-low res still images or video on a spinning 3D screen. That's accomplished using a single ring of tri-color LEDs, which spins at a rate fast enough to display any combination of red, green or blue pixels along the surface of the resulting sphere, giving you an impressive 3-bit color depth (no video of it in action though, sadly). That, of course, is slightly easier said than done, and there unfortunately isn't a step-by-step how-to to guide you through the process, though we're guessing anyone actually pondering such a project will be able to make do well enough on their own.

comes with free ecstasy.
I think they ran out of ecstasy!
But is it as trippy as speed racer?
The ecstasy means nothing if they don't hand out pacifiers for the kiddies to suck them with.
Anyone whos been to the O2 in london will have seen better versions of these around entertainment avenue, their one strip of LED's which rotate really quickly giving the impression of a full display.. look at them too long and you get a terrible headache though
the onnnnnne post that needs a video more than any other...
My kid has something like that from the dollar store.

I've had something similar to this for a couple years. Bought it from San Francisco (The Store) for about $20. It even pulses to music/sound.
Walgreens sells something like this but I think it only says one thing or it shows the time of day...I forget.
ROSEBUD.................
Looks like the Deathstar plans are in place... Ruh roh!
I'm sort of glad I'm not the only one who thought of that.
Do not touch.
Didn't the Adventurevision's display work this way? A row of LEDS & a spinning mirror?
Here is a commercial display that is cylindrical instead of spherical.
Pretty cool...
I don't think this one relies on persistence of vision though.

but DOES it blend?
Just 48 LEDs?
I found ver batim, the exact same story. Crazy!

Who the hell is that in your avatar and what have you done with Tails.
