I remember when the Nintendo Game Boy came out back in the day and we were all super excited that you could play games on the go. The graphics were terrible though. If you want to relive that mobile retro gaming action, the Game Boy 16oz heat change mug is just the ticket.
This square coffee mug holds 16 ounces of liquid. If said liquid is hot, it will change the black screen of the Game Boy on the cup into a green screenshot from Super Mario Bros. It’s made from ceramic, but you can’t microwave it due to the special heat-sensitive stuff.
The mug will set you back $12.99(USD) at ThinkGeek.
