Anyone who’s tried capturing a moving video will attest to how difficult it is to keep the camera steady without an expensive rig. And since some the folks at MIT Media Labs had the same trouble to solve with limited budget, they created the CineSkates ($150). The CineSkates are four wheels that attach to a GorillaPod Focus, a tripod made for DSLRs. This smart contraption will allow you to capture smooth, fluid video without breaking the bank.
