This circuit sculpture makes use of brass rods as conductors. It has many carefully made bends to complete the circuit and add aesthetic appeal.

The brains of the system is a AT-Tiny85. A MAX7219 IC is used along with the AT-Tiny to drive a 8×8 LED Matrix.

What’s different about this project, other than the visual appeal is that the you can display any text(scrolling text upto 16 characters) or pattern you want on the display without reprogramming the chip. This is achieved by using V-USB to enable the AT-Tiny85 to act a USB device which can receive data from your computer using a custom build app in C++
