Review

Works pretty well.
I had the same lock-up as another user but I resolved it with terminal and hte command:
pkill Videowall

After the first time, it started without the lock-up. My use for this is different than most. I wanted to be able to monitor a webcam. Works well for this, but as noted by other reviews it does use a good amount of CPU. On my Macbook Pro with Retina Display that had 16 gigs RAM and the Fastest Macbook Pro processor, it take 35% of one processor. If it werent constantly consuming that much, it wouldnt be a big deal. It is enough to kick my fan on and I rarely have my fan come on. At least I rarely have it fast enough that I can hear it.

Works well for me outside of these two issues.
