In the demoscene I usually use the handle yugecin.

A demoparty is an event where demosceners and other computer enthusiasts gather to take part in competitions, nicknamed compos, where they present demos (short audio-visual presentations of computer art) and other works such as digital art and music. A typical demoparty is a non-stop event spanning a weekend, providing the visitors a lot of time to socialize.
