While fooling around with a mini-lcd-pictureframe which was given to me as a key-ring (as this it is quite useless IMHO) I suddenly thought "Well, this could be used differently?!".
So I proudly present:
Comes with a mini-usb-port to connect to the computer and a slideshow function which lets you demonstrate your feelings about ... well anything you can squeeze into the tiny 200 by 200 pix image-format.
All I did was drilling a little hole in the back and with this and a lot of plastic glue (take what you find suiteable) i fixed the knob of a removable holder from a surplus PDA-hardcase to it.
Even wearable for the people who have to wear suits at work.
Of course one of the images on my new tech-button is the mobileread logo
