So I had this idea as I was eating blueberry waffles and watching family guy (Which I rarely do):


I'm using this for my scratch graffiti removal biz (San Diego Glass Restoration ) one application is simply taking it to a shop owner with damaged glass and saying "here we can do this for you, and save you $x on replacing the glass).
I lined up a $250 scratch removal job while eating lunch at quiznos just because I brought that in with me while I was eating, but some jobs we do are worth a lot more than this little 1 pane job
I have a LOT of these bad boys, I have some pretty neat plans for some of them but am seeking ideas for what I could do with the other bunch of them I have.

Lets here your best ideas!... What else could I use a fat stack of these "portable porthole demos" for? they fit perfectly in padded envelopes
