Check out this idea: this company called Bespoken Art will take a sound recording you submit or a word and then materialize the sound waves on a canvas. For example, I could send in the word "Glitterature" and I would get a canvas back that looked a little like these (I wonder if they could make it out of gold glitter...):

Thoughts? Not sure that I would necessarily put one in my house but a unique idea for personalized art.
