Mark sez, "I brought a few Edison Cylinders in for the elementary kids we're coaching for a Maker-like school competition called Mind Games here in Richmond, VA. (Innovation, compare to iPhone, etc). Since they'll be returning to the idea later I thought some pics would save the 100-year old pieces a grubby-fingered death. That's where the 35-cent price floor jumped out at me. I knew he was brutal about IP, but dayyum, international price cartels too?"
EULA - End User License Agreement. Edison invented that, too (Thanks, Mark!)
