I saw this kind of UI (bit more colorful) back in the 80s while reading some catalogs from HP. It was in USSR. After I first saw it I absolutely loved it and had spent next 3 month writing low level assembly graphics and was able to replicate it in my programs written for generic PC. Implemented threading inside program as well.
