Photographs transport people to earlier times without the need to master quantum physics or pay the tolls associated with America's wormhole highways. Capture fleeting moments for future examination with today's Groupon: for $499, you get a four-hour photo-booth rental from Think Event Group (a $1,300 value). Photo booths can be delivered to locations within Beltway 8 for free, or to locations within 150 miles of the beltway for an additional travel fee.

Think Event Group's roving shutterbug attendants set up photo booths at special occasions to help partygoers capture spontaneous zaniness. A personal concierge sets up the camera station and the 5' x 5' tent that houses it, with room enough for 10 adults posing or playing five-on-five basketball. Simple on-screen instructions aid in the shot-snapping process, allowing guests to take unlimited pictures during the four-hour rental. People being photographed can take their pick from a stock of included props, eliminating the need for outdated bunny ears or awkward prom poses. Two 2" x 6" prints pop out of the machine within 15 seconds of each shoot, and every image is uploaded to an online gallery for future perusal. Clients can customize the printing strips to their preferences, such as choosing between black-and-white or color images.
