Never mind about the mouse pad if the pieces should be rigid. I have a mouse pad that’s probably a little thicker than a quarter of an inch, and I thought it might work because the underside has a crisscross pattern that might grip; but no, it isn’t any more dense than any other foam mouse pad. I have the gripper stuff, so I’m happy with what I have, but I might try a more flexible material like the mouse pad someday just to test that huggy feel inamo describes.
And I was thinking more about marketing possibilities… Maybe you could mainstream it. Buy full page spreads in the back of men’s magazines and infomercials on late night TV. Sponsor a college bowl game and a Nascar team. Then, use the proceeds to finance a chain of Pirate-themed PE lounges. Put the first in Key West and have Pirate Steve manage it. He’s got a ready-made market with all them nekkid people running around down there.
