Here’s my project, “Success”
The user wears a glove which corresponds to a finger poised over a bowl. Making a grabbing motion while wearing the glove causes the finger to reach into the bowl. Inside the bowl is a light, which gets brighter each time the finger tries to reach into the bowl. The finger will also reach farther into the bowl over time as well. Eventually, once the light reaches its maximum brightness, the finger stops working, and the light fades out.
I had some issues conveying the grabbing motion. If I were to redo this, I would make a full hand and figure out a way to tie all the tendons in the fingers to a single servo, as I only wanted to use one servo. Also, the flex sensor wasn’t terribly accurate, and thus can be a bit twitchy. I could have also filtered the sensor values to smooth out the motion. The last change I could have made was to use a lightbulb instead of an LED, but I was wasn’t sure about the external power requirements it would require.

I really enjoyed your project, It was simple but compelling, and though it didn’t work perfectly it worked enough to show the direct influence of my bending my finger to bend the straw-finger. It was fun to try, and rewarding to watch the little green finger move with mine
I really enjoyed the interactive component of your project, and I thought that linking the servo and the string to control tension was very clever. I thought your concept was great as well, but I think it was a little too high-level, and perhaps a bit difficult to understand if there was no explanation. I think it would help if you made the LED more obvious that it was the goal of the finger, like by making it a jewel (placing a translucent acrylic jewel-shaped cap over it or something) or other generally appealing object.
