If you're just looking for visual effects, poke around a Rainmeter skins site. I believe there is a Steam Wheel skin available for it. You can place shortcuts to whatever games you want (not limited to Steam) on it. The menu itself appears as an overlarge Steam logo on your desktop - when you press it, it expands into a wheel with shortcuts.
I tried it, but didn't like it. I felt dumb taking time to open a wheel when I could just run the game thru a normal desktop shortcut.
EDIT: Aha -
