There's something inexplicably satisfying about a ball that sticks on things. Tossed gently onto any smooth surface (whiteboards, computer monitors, glass ceilings), and it stays put. Draw a target on the whiteboard, and you have a game.
Draw a decision matrix like this one and you have an Emergency Arbitrary Discussion Concluder. Sound silly? Consider those high-level, $5,000/hour executive discussions about the relative merits of plastic vs. metal paper clips. A fun and quick way to bring these conversations to satisfactory and permanent closure can save significant dollars and many a misspent temper.
For the sake of potential ambivalence, you can give everyone a Suction Ball (be careful not to refer to this as a "Sucker Ball" - though it adequately describes the device, the inadvertant implications of the term "sucker" can cast a certain negative aura which might impede enthusiastic and wholehearted participation) and have the decision determined by taking the average of those balls that are still stuck by the end of the meeting. To add drama and intrigue, people can take turns throwing their Suction Balls. This gives participants the opportunity to try to knock each other's Suction Balls off the target, in a kind of vacuous vertical shuffleboard exercise. To bring things to a quick and appropriately meaningless conclusion, everyone can throw simultaneously. Since Suction Balls can suck on to each other, extra recognition can be given to anyone who is able to perform such a remarkably senseless feat of accidental coordination.
Finally, rolling a Suction Ball across a the surface of a conference table produces a satisfyingly annoying popping sound, which, in turn, can be used to signal a felt need to continue to the next item on the agenda. If everyone has a Suction Ball, this same signalling mechanism can be used as an applause-substitute, as if to say "aren't we on a roll now."
