Final Results

Picture below is the final assembled prototype, with all electronics wired up. There are in total four tea leaf jars, all mounted to their respective turntables. There are also spotlights above each of them. The only design component not illustrated in this prototype is that in the actual design, the shelves would be made of much thicker wood to support guests climbing on them, and there would be easy gripping features on them. The wires would also be hidden inside the shelf boards.

Pictured here is a close-up of a tea leaf jar under the spotlight.

Here is our demo from the final presentation - enjoy!
