Steam now has a maddening bouncing logo screensaver, and I'm pretty sure it doesn't perfectly hit the corners

The Steam client got a major new update today, with Big Picture Mode receiving the brunt of the attention. Most exciting, I guess, is that the previously beta-only screensaver feature for Big Picture Mode is now live for the general public. In its default mode the screensaver will display art from recently played games, as well as any recent screenshots you've taken. But you can add your own custom screensavers too, which is nice. Valve also has "a retro inspired bouncing logo screensaver" which you can select in the new dropdown menu found under Settings / Customization.
