Fun toy to introduce a three year old to the concepts of electronics.


Stacklight is an educational toy for kids to introduce electronics in the appealing hands-on way.

The goal of the game is to introduce electronics through big objects, colors and shapes. We want to encourage kids to recognize patterns, organize and play by stacking the objects.

User age: ~3 year old.

How does Stacklight work? Each of the Stacklight pieces light up as the kids stack them.

Physical snowglobe creates digital snow over a live webcam footage


This project consists of a screen displaying a live webcam of NYC. On a small platform in front of the screen will sit a snow globe with the same NYC scene shown in the webcam within it. When a user shakes the snow globe, it will appear to snow in the live webcam. The speed and direction of the snowfall onscreen will mimic that of the snowfall in the globe.

The snow is a p5 simulation that connects to an Arduino in the bottom of the snow globe via serial communication. The snow simulation code is controlled by reading and mapping values from an accelerometer. Currently, the NYC webcam footage is actually a recording but we plan on directly embedding the live NYC webcam footage for the winter show.

This project playfully leverages the prevailing belief that live webcams represent the truth.

Melanie Hoff and Shir David created this for Benedetta Piantella's PCOMP mid-term.
