Liquid Lifebar Represents Your Health Meter With A Physical Water Tube
A talented engineer and programmer has created a water tube that raises and lowers its water level to represent your life or mana meters.
The video below shows the building process, as well as the tube in action while bfayer plays Terraria. Lights have also been added to make the whole project that much more magical. If you're impatient you can skip to the 4:42 mark to see the liquid lifebar in action.
