Here is an LED bracelet I made. As you can see, it doubles asa cat fashion accessory although Yin and Yang need convincing. The bracelet currently has no information content, but just you wait for Bracelet 2.0.
I learned how to sew circuits, make a battery holder in elastic, and make bead designs with thread. Oddly, all much easier than the felt puppets (Borg and co). I think it's just much easier to work with satin and fine conductive thread.
