One of the MIT photography classes that I took online using the above link was a class on how to build your own digital camera. This course challenged me to think outside of the box when it comes to using digital cameras. I've previously made some minor mods to my camera sensors, but now after watching this MIT course, I'm going to try even more extensive and exodic mods to my cameras.
I'm surprised that these free photography courses didn't inspire anyone else to explore new photo methods/techniques/mods too...
