Found it! Through sheer Google-fu, I discovered ThinkBlot!
Tom Vasel's review describes its use:
The game is very simple. Up to six players are given a sheet from a pad included with the game, along with a pencil. Then, the Thinkblot book is opened. It is a spiral bound book that transforms into an Easel with 75 different inkblot pictures, as well as a fold-out scoreboard. Each player places a peg into one of the colored paths on the scoreboard, representing his score.
Now, a special 12-sided die is rolled. Instead of numbers, there are little pictures or blots on each side of the die. Depending on what is rolled, the players write down things on their scoring sheet that they think they see in the inkblot currently showing. Whenever a little blot is rolled (eight of the twelve sides), players write down anything they see in the inkblot mess. When a little bug is rolled (one side), players should write down any creature they see in the picture. When a little face is rolled (one side), they are to write down people, parts of people, or actions taken by people. When a half eaten pear is rolled (one side), players should write down any food they see. And when a little shirt is rolled (one side), players are to write down any clothing or accessory they see.
