Entry no #3. In addition to artificial dots made with brushes, it also boast a real polka theme unlike all other entries, and also has a nice composition. Sure, it is a bit big and borderless, but it's not that much of a deal in this entry. And seriously, the text isn't THAT bad, you don't even see it at first. But yeah, probably the only Polka theme sig that actually did the theme right.
For the popular #1 entry, I can't even make anything out of it >.>
