Heat change mugs like this one will help gamers get the caffeine they need when their own bodies need to refuel. An exclusive creation from ThinkGeek, the Ready Player 1 Heat-Change Mug transforms when filled with a hot beverage.
The 11 ounce cup reads 'Ready, Player One Start' when it is filled with warm contents. However, if your tea, coffee or hot chocolate has gone cold -- or the cup is simply empty -- it will say 'Game Over, Refill? > Yes No' instead. This is ideal if you are addicted to coffee (or other hot liquids) and retro video games. The ceramic heat change mugs make a great gift for any coffee-guzzling gamers in your life.
