Dumpster 23

You open the lid of the dumpster, and peer inside to see . . .

. . . a yellow and white checkered sphere bearing four faces painted in black. As you turn the heavy object over within your palms, you hear a series of faint clicking noises coming from within. Reaching into the crate again, you pull out a manual entitled, simply, "The Mark One Spinning Face - Deadly accurate. Pneumatic-driven. No system clocks. Will never crash." The rest of the manual is written in a pictographic language you are unable to decypher.
