You can choose just about any well known brand of mass produced iron as a base unit. Your Face Ironing Your Pants, will scan in your photograph, convert it to a series of dots, like a halftone, which will in turn be manufactured as the pattern of steam holes on the face of the iron.

You can use it just like any normal iron, or exhibit it from time to time on a shelf, with steam visibly hissing out of the dozens of holes that now look like your face. Leave it sitting in place too long and it burns a nice portrait into your laundry.
