Events

While competitions are surely the main events at any demoparty, we also will bring you even more to enjoy during the event.
For those who want to improve their skills or just inform themselves about interesting, computer- and demoscene-related topics, we will host some awesome seminars.

And to emphasise the "party" in "demoparty", there also will be some top-notch liveacts playing for your pleasure!
