Hi!
Thats my IR-fingertip ;D The idea is not new but I have never seen someone has really made
one. Its built up from a foilbutton with pressure point, a clear polythene sheet as skeleton and
a lot of hook and loop fastener. The IR-LED is mounted backwards facing above the fingernail.
It works nice and makes a real "touch screen feeling". When I have painted the foilbutton white
I will try to show you a short video.

Very cool, I like how you are pushing boundaries with IR-sources.

Any chance of an instructional video too?

Found it here Artikel-Nr.: 709905 -LN

Edit: Because tracking with the backwards facing LED is not that good I will try something like that-

Have you tried a surface mount IR LED.  It would lay flat and point straight up.

No, but I tryed something like that and I decapitated the LED.
Now the wiimote can see the LED all over the whiteboard but
you can only click things, drag isn't working. I think total radiant flux
is bad. Its really frustrating.  :'(
