Vessyl
From Just Solve the File Format Problem
Vessyl is a "smart" drinking cup which can detect what sort of liquid is placed in it (even down to brand names), and keep a log of what you drink and the calorie counts associated with it. If you want to spend $99 (reduced from $199!) for a cup that's not the Holy Grail, this is the one to get!
It seems to sort of detect beverages the same way Shazam detects music. It can sync with smartphones to relay the results.
Despite the silly-spelled name, apparently vessyl.com was already taken and they had to settle for myvessyl.com.
While making fun of this on his show, Stephen Colbert referred satirically to a "smart toilet" named Toylyt, but there actually is a product of this sort.
