halfull
Does the word "halfull" have any pun? The only think that I can find out is that it is composed of "Half" and "Full". Does it have any other meaning? It is a word artwork by Kay Rosen that could be viewed here: http://kayrosen.com/work.html

Question

Answer

Yes, it seems to just be a pun based on "half" and "full." Looking at the image, you can tell the word is colored seemingly like a car's fuel gauge, going from orange to yellow to green.
It could also be based on the classic "pessimist or optimist" quiz (if you want to call that): a glass is filled halfway with water; is it half empty or half full?
