Mahalo Moment: Colour-Changing Lucky Cat Aloha Mug

I stumbled across this when browsing in Lahaina during our recent Maui trip:

Notice how the colour of the mug changes from the first photo to the last? Yep, that's right, the mug transforms according to the temperature of the contents. So when it's full of hot coffee, the pink floral background is displayed. But when it's empty or the coffee is cold (boo), then the background returns to all black. So fabulous!
