Just wondering if anyone has tried pulsing the LEDs and trying to read the resulting signal from the Wiimote.  My guess is that there are a number of reasons why this won't work very well, the frequency of update of the camera, bluetooth issues and the need to continually poll the wiimote state to get something that won't be very reliable.

Nevertheless I keep coming back to the idea.  I want to set up a number of beacons around the room, so that when I point at a particular spot in the room (whilst moving around) the software will know what I'm pointing at.  Plan A is to use encoded shapes - but this is a lot of LEDs and no scope for overlap.  Even low frequency pulsing, like little lighthouses, might work better. 

Any thoughts?

there is pictures of a pen that is controlled by a PIC processor and it has 3 buttons, in order to tell the buttons apart they pulse so the program can identify the button and execute the command for that button

its in here-  just have to search...

it tells me that pulsing the leds should work - but if it works as you want it to, i cannot tell...

interresting idea...but the wiimote can only handle 4 points at 1 time...
