Novelty heels with custom infinity mirrors installed. I found these heart-shaped heels and used a laser cutter to precisely cut mirrored acrylic to size for the mirrors. The electronics include a Qduino Mini microcontroller programmed with Arduino and 5mm addressable LED strips.
Read about how I built the project on the SparkFun blog - Fashion Hacking: Infinity Mirror Heart Heels.
The black wedges use six custom modules that are installed into the heart cutouts. The white wedges have one large infinity mirror installed in each shoe.
