I did this about a month ago - didn't want to bump this thread just to show one picture, so I guess I'll bring it up now. It's 6x6, with I think 3mm dot sizes. Looks awesome. It actually didn't take me all that long to tape together since I wasn't worried about making it look perfect (I'm moving out of the dorm in a few days - didn't make sense to spend a lot of time on something that would only be up for about a motnh).
