No matter what you enter, it has at least one use..as an entry in the contest.. and therefore it isn't useless.
The rules say useles..not useless accept for in this contest...bo by creating the contest, and not specifically excluding the aplication of an entry from the definition of useful. You have created a contest which according to the current rules & guidlines, cannot be won no matter if you enter a picture of a particularly worthless politician, or a pencil breaking machine.. it's got one practical application as a contest entry .
