The BrickUniverse convention held earlier this year in Raleigh was well run and fun, even though the fan-provided MOCs were in short supply. Greyson, the event’s creator, has already fixed that problem for his convention coming up in November this year. I don’t know if Greyson came up with this idea, but it is brilliant; provide enough creations to fill 8 feet of table space, and your ticket could be free (Details) . For every 8 feet/additional 8 feet, you also get a freebie of some sort.
