These LED fans have 5MB of memory and will spin-animate any series of bitmaps you load onto it — alas, it requires you to use something called "Windows" with it.
5 megs of memory holds up to 128 individual frames. You can animate, spin, slide, flash and dissolve to your heart's delight. All the while, enjoying the cool breeze from a chromed-up art-deco desktop fan.
Show off your m4d 4rT 5k1Llz using the included software. Import animated GIF files, or draw your own frames. If you've got a logo you want to display, have at it!
