T-Shirts that pulsate to sound??

The coolest thing I saw at Wizard World Philly were these T-shirts that actually light up and pulsate to sound. Seeing this in person is crazy!! They go by the name EFM (Electro Flash Media), and seeing it in person is pretty freakin’ sweet!

You can find them at Booth 801 @ Wizard World Philly in the Philadelphia Convention Center.
