This amazing wall clock can display intricate animations thanks to the optical phenomenon known as persistence of vision (POV). Using a small spinning “blade” covered in red, green and blue LEDs, along with sophisticated microcontroller circuit, this clock can dynamically change its look with just the push of a button…

Hardware hacker Ian Matthew decided to see if he could turn a hard drive into a clock. But this isn’t one of those lazy designs where you just stick some clock hands through a hard drive platter. On the contrary, Ian went way over the top.

A narrow slot cut into the platter allows a set of flashing colored LEDs to show through as it spins…

In the beginning, there was the roller skate, then came the skate board and later the Rollerblade. So what’s the next conveyance that we’ll be strapping to our feet to roll around the street?

Orbitwheels move sort of like inline skates, but a wheel rotates around your feet, instead of under them…

The guys from online shop MyVirtualZone just tipped me off to these little playthings. The appropriately named Laser Top has a little laser beam that projects out of the side as you spin it around.

While I actually think the effect of the LEDs and the laser are pretty cool when its spinning, I think that the music that plays as it goes is about as ridiculous as it gets…

By rapidly spinning a blade that contains an array of flashing LEDs, this wall clock tells time in a visually striking way.

A thin LED arm, loaded with 33 LEDs spins at 30 revolutions per second to create the illusion of a complete image. When the blade is spinning at full speed, it tricks your eyes into thinking there are nearly 8000 LEDs…

ThinkGeek is at it again. This time they’re offering up a fan which can load up animated GIF files from your computer and display them in full color on the blades of the fan…

Some sick individual strapped their buddy to a seat at the end of a FANUC industrial robot’s arm and then ran him through the spin cycle.

They captured all of the fun and festivities in this video clip:

I wouldn’t want to be the one sitting in that chair. I’m feeling a bit nauseous just looking at it…
