Free Online Screen Recording

When I was attending P2PU Massive Open Online Classes (MOOC) class called Machinima, I learned about Screencast-O-Matic, a free online screen capture recording on both Windows or Mac computers with no installation required.

In the short screencast  above, we were in Second Life and I was having a problem getting on the cube so I was not able to jump on one like what the rest of the other participants are doing. I was graduating at that time and busy with my internships and Networking class so I wasn't really able to devote as much time to the Machinima class as much as I want to.

Another free online screen capture recording with nothing to install is Screenr. You can record your screen on both Mac and PC and the screencast even plays on iPhones.
