If you have a friend for which a regular holiday card would be far too analog, flaunt your geek street-cred by sending them an edge-lit holiday card.
Creating a glowing holiday card may not be the most economical for a mailing list of hundreds of people, but as a one of a kind creation it's a remarkably cool and cheap DIY holiday creation.
By taking advantage of the properties of etched glass— in this case acrylic— tinkers at Evil Mad Scientist Laboratories were able to craft greeting cards with glowing emblems on them. The cards are made from LEDs, scraps of acrylic, cardstock, black electrical tape, and coin cell batteries. Many of the items are things that a self-respecting tinkerer would have on hand. If you think that LEDs and holiday cards are a match made in heaven, you'll definately want to check out the super cool 3-D LED christmas card in our DIY Christmas Card Roundup.
