Crochet around a rope light to create a light-up rug. Good for; Christmas tree skirt, seasonal decoration or just because it's really neat. No instructions in the link, just follow a pattern for basic flat spiral and stitch around the rope light.
Mirror frame made from leftover toys & spray painted. Very cool for a children's room I'd like to do this with salt dough hearts and red and white paint for a kind of Queen of Hearts style bedroom mirror :)
