Glass provides a resting place for wine, evening wear for Cinderellas, and a more dramatic exit from 44th-floor windows for Bruce Willises. Shatter artistic inhibitions with today's Groupon: for $25, you get a two-hour introductory stained-glass workshop at Rainbow Vision Stained Glass (a $50 value).

With more than 26 years' experience designing and teaching, Rainbow Vision's instructors foster an inviting atmosphere, in which beginning students relax and have fun while learning to envision, design, and create stained-glass window panels. The two-hour introductory stained-glass workshop teaches students the basics of cutting glass into various shapes, such as daisy petals and Mark McGwire. Stainers learn to employ copper foil to prepare pieces for soldering and how flowing solder between colored shards holds together the colorful designs. Ultimately, neophyte artisans combine included class tools and their newfound skills to foster the creation of a 6-inch circular window medallion that can be used to transmit not-so-secret floral messages or showcase successful Risk strategies.

The windows of Rainbow Vision's Victorian mansion glass studio are lined with sheet after sheet of tie-dyed, dream-bedazzled shades of glass, each providing shiny inspiration for new students. The maximum class size is capped at 10 people, and classes are usually led by two instructors per class to encourage a supportive learning environment and intimate dance-offs. Current class times are scheduled for Tuesdays, Wednesdays, and Saturdays, but additional dates will be added throughout the duration of the Groupon.
