LEGO is selling a new ice tray that pops little LEGO brick of ice. This means you can build your own LEGO ice sculpture. The $10 LEGO ice cube tray is made out of silicone, dishwasher safe and capable of making up to 10 ice bricks.
Implications - If you've always dreamed of visiting the ice bar in Sweden, but can't seem to save up enough money, you could always construct your own mini version out of the LEGO ice cubes you make with this tray. If you were really patient and creative you could take the time to create enough ice bricks and make a life-sized frozen structure, but you'd have to do it during the winter months to avoid it melting.
