Tanga offers the UbiRock Portable Vibration Speaker
in Alien for $12.99. Coupon code "UBIROCKNOW" cuts it to $10.99
. With $4.99
for shipping, it's a buck under our mention from two weeks ago and the lowest total price we could find by $46. Put this speaker onto a solid, flat, rigid surface and it makes the underlying object radiate sound (more or less turning it into a speaker).
