Halloween party set:
Wrist picture frame
Always some pictures to show, just around your wrist. Spooky pictures during Haloween.
And for your kids, scale it down a little and write address and phone number at the back of the pictures in case they (the kids) get lost. Depending on the thickness of the paper you can store about ten photographs. How to make 32x32mm (or smaller) pictures? Download square photographs into Word. Click them and then, right click to see the size and change it. Many photo’s on one page can be printed and cut out easily.
Just two leds, a resistor and a battery.
Printed in white, or even better, glow in the dark. Some red lipstick on your chin and people start running.
