Coffee Mug Warmer
Everyday life has plenty of unavoidable indignities; there’s no reason to add cold coffee to the list. We’ve come so far technologically, yet we’re still relying on basic pottery to keep our coffee warm, like it’s the Stone Age or something. People are just too busy to pay attention to how long their coffee mug has been sitting out on the desktop. Place it on one of these instead, and they never have to worry about it again.
