An early-summer computer and demoscene gathering returns to Lohja’s Partioniemi on June 5–7, 2026. The event blends classic demoparty spirit with relaxed lakeside vibes: live demo shows on a big screen, a digital competition category and hands-on LAN “ATK culture” such as sharing public domain games and burning Linux distributions.
Participants can reserve limited computer spots, sleep on-site (beds, floor space, tents), and enjoy a well-equipped kitchen, grill, sauna, and swimming in Lake Lohjanjärvi. Friday is for setup and socializing, Saturday is the main demoscene and computer culture day.
