Great Overall
I wish there were a couple more tank style choices, but, hey, it’s beautiful! The only glitch I have found so far involved startup at boot. I have clearly checked to see that it DOES NOT start up on boot, but it does anyway. I am running OS X 10.10.3. This is more of an annoyance than anything else, because I prefer it to my other screensaver apps anyway and would probably start it most of the time after I boot.
