Let's play a game.
I post an image of an object. The next poster then posts a picture of another object that will combine with my object to create an invention. Give a name and brief, one sentence description of what the invention does. The next poster then makes a new invention based off of the previous poster's image ONLY (excluding all previous combinations/inventions). The most any invention will have is two objects: yours, and the poster's before you.
They do not have to be feasible, or realistic. In fact, the more ridiculous, the more encouraged.
