Digital technology has allowed for the introduction of many new art forms, just as Leonardo da Vinci once predicted on his blog. Upload a masterpiece with today's Groupon: for $499, you get a four-hour rental of a double-sided photo booth from Phoenix Photo Booths (an $1,100 value).

Founded after the owners crafted a booth for their own wedding, Phoenix Photo Booths supplies double-sided, party-ready snapshot boxes that double the number of candid shots possible. Between staging photographic recreations of Whistler's Mother, photographees can add eccentric touches to photos using a box of props. Guests can take unlimited shots, which will be uploaded to an online gallery for at least 12 months and loaded onto a CD until it crumbles into rock candy a century later. Renters procuring booths for weddings, holiday fetes, and other occasions must provide a solid, level area large enough for the booth and within 20 feet of a standard electrical outlet.
