The rules of this game are simple: it is like word association, except instead of coming up with a word, you must draw a picture. This may or may not have a title, and if the picture does have a title, the next picture may be related to either the appearance of the picture, or the caption.
I will start with an initial image, and the next poster must create and post a related image, and so forth.
Also, there is no required format or medium for the images - they can be as detailed or as simple as you like or have time for - but they must be original.
