This is the Beacon yoga mat, it uses LEDs and pressure sensors to let you know when you’re doing it wrong. Not to be confused with the Bacon yoga mat, which sounds delicious but only exists in my dreams. The mat turns purple to show the correct position, shows red where you’re applying too much pressure, and green when you’ve got it all right. But does it quietly mock from the back of the closet? Because mine does that and it isn’t even equipped with any kind of fancy tech stuff. It’s rude! And definitely not good for my chakras or whatever.
