Ancient Romans crafted mosaics to adorn ornate churches, depict historic conquests, and help Rome use up its massive surplus of tiny square rocks. Clear the way for artistic creation with today's Groupon: for $30, you get an introductory mosaic class at Glass Mosaic Canada (a $95 value).

Passionate mosaicists at Glass Mosaic Canada inspire and equip budding artists to skillfully construct multifaceted mosaics. During a 90-minute Saturday tutorial, a small class of apprentices delves into the basics of mosaic composition, from cutting colourful tesserae to sealing and grouting shapes into handy models of the human genome. Provided with the proper tools and materials, students set to work at the relaxing and satisfying task of adorning an 8"x8" plaque or an object of their choice that they have brought along. More experienced tile wranglers are also welcome to attend class and receive further instruction on deftly assembling tesserae. Like building an igloo out of Rubik's cubes, the combinations of tiny tiles are endless, and students are encouraged to stay for supervised open studio time after class to lay the finishing touches on their shimmering creations.
