Bulbs won't work. The article is better than its heading, though. (LED do work.)
On a similar note I was wondering if the iPhone (screen or elsewhere) could produce enough IR radiation to function as a TV remote? Any thoughts?
Perhaps flash the screen backlight to produce IR signals?

You'd have to flash it at something like 38 kHz, but I have a feeling it doesn't support that.
Only problem: pockets
I wonder how two-way communication would work - flashing your laptop screen?
probably a dedicated peripheral, which you need to capture the light patterns anyway (right?).
What if I work in the dark?
It is incredible what can be done with low cost micro-controllers and a little low-level assembly know-how.
