The document describes an E-Ball, a spherical computer designed by Apostol Tnokovski. It is small, with a diameter of only 6 inches and a 120x120mm motherboard. It contains wireless keyboards and mice that use infrared rays, lasers and RF signals. The E-Ball has large storage and memory, and can project its display onto surfaces using an LCD projector. While portable and useful for presentations, E-Balls have high costs and compatibility issues, and troubleshooting hardware is difficult.
