I don’t know about you but I wouldn’t be able to resist leaving tips if I saw this in action somewhere. It would be great if it could detect what the value of the tip was and if it had different actions. Perhaps its charm is in its simplicity.
From a young age I've been a big fan of all things weird and even though I love science I love the passion that people involved in the spiritual and fantastical side of things possess. I want to believe in aliens, bigfoot and the world of psychics and superheroes seems that much closer when you investigate the weird world out there.
