This document presents the concept of the E-Ball, the smallest PC designed by Apostol Tnokovski in 1982. The E-Ball is a spherical computer around 6 inches in diameter that contains components like a dual-core processor, RAM, hard drive and ports. It projects its display and virtual keyboard using an embedded pico projector. The E-Ball is portable and allows presentations without needing an external display or keyboard. While innovative, it also has drawbacks like needing a plane surface for projection and typing.
