Last night I came upon a giant cube. It was perhaps 15 or more feet tall and just as wide. Right on the northeast corner of 18th and Columbia Rds, NW. There was a film showing on one side. Apparently a promotion for HBO. Inside various Adams Morgan bars, mini cubes to complete the promotion. It's called the Imagine Cube. Pretty neat. I don't have HBO though. I did like the Sopranos when it was on TV.
