I found these cheap LED rings. I guess with a little work it can be adjusted to IR.

I have one of the LED rings but you would need to change the switch because its will either flash or stay one.  So you would have to click twice to turn it on then off.

Oh.  :(
But I guess it will still be effective for some kinds of interaction (like the VR stuff) where you need it always on.

yes very true, this would be great for VR if you where normal eye glasses you could strap these on to the frame.

Here are a few more ideas:
I found them with companies specializing in "marketing collateral", so its probably junk you can find everywhere:


Using two of these, and switching the 3 leds inside for 3 IR leds (preferably the 100mA kind) will give you a flexible platform to clip on to a baseball cap for example.
They sell something pretty similar here: http://www.southsummit.com/catalog/product_info.php?products_id=3934


I didn't actually get down to doing this project, but this clips on to the front of a baseball cap too. If you switch the side leds for IR, you could use it for VR.
This site: http://gadget.brando.com.hk/prod_detail.php?prod_id=00140
sells them for about 16 dollars, but with a bit of creative googling, (baseball cap 5 led) will probably bring up some results close to you.
