Your morning cup of coffee can be a dreary moment. It's not lunch time yet, you have a mountain of things still to do that day, and no one's noticed the new jumper you're wearing even though it has a cat burglar on it. Brilliant. It's almost enough to ruin your day BUT WAIT. What if your morning coffee was actually a wonderful moment? What if it made you smile and caught the envy of everyone around you? ALL THIS COULD BE YOURS!
How about a Tetris heat change mug? You pour your hot drink in, and then watch with pure joy as the little Tetrominoes (that's Tetris bricks - they have a name!) appear and stack into place. I know! How could that possibly get old? And it's only £7.99 from iWOOT.
You can also have uber fun watching the Pac-Man heat changing mug. Sorry, the little ghosts don't actually chase Mr. Pac-Man himself, but it's still awesome to watch them all pop up on your mug. This beauty is £6.99.
Or how about the epic Space Invaders colour change mug? Row upon row of pesky aliens appear in glorious colours. It's £7.99.
