Thumb Thing

This piece of plastic is meant to be worn on the thumb, where, if you hold a book a specific way, it will push the book open. It probably works, if you read a book in that specific way. Nonetheless, there is an artisinally-handmade version for three times the price, or, if you want to go all the way, a cantilevered floor stand for holding your book for thirty-seven times the price.
