I actually did this yesterday. I whipped up an infrared LED finger attachment to use to control my computer with my wiimote, and because I did this in a location different than my computer I had no way to check if it worked. Quick thinking and I pulled out my phone and BINGO my LED’s were working.

This reminds me of something I did recently.
I whipped up a quick programmable logic configuration to multiplex four 7-segment LEDs @ 1 kHz, sufficiently fast that you can’t see that they’re multiplexed.
I decided to point my digital camera at it in its fastest shutter mode. Looking at the LEDs through the camera’s display revealed the scanning pattern!
