Since 2003 we are offering a great discount for those who love demopartying: The Evoke demoparty in Cologne and Demodays in Olten bring you the Combined Ticket. We will provide a nice discount for those who visit both Evoke and Demodays this year. Just buy the Combined Ticket at Evoke for both parties and get a 5 Euro discount (the price for Demodays in Euro has not been disclosed yet).

Update: The price for the combined ticket will be 75 Euro (instead of approx. 80 Euro, depending on the exchange rate)

It's all new about our competitions: We bring you a fresh categorization and two thrilling new competitions - all of that to keep things interesting at a small party like ours. For the first time, you can take part in the new Mini-Animation compo, where it's your job to create a 10 seconds animation (without music) that will be looped for 1 minute. No time to produce a full-fledged animation entry? Mini-Animation allows you to show your skills in less time. For the species of photo addicts, there's the new Photo Retouching competition: We decided against a pure photo compo and want to see your retouching skills - show what you can do best!

Because we lacked entries in some categories in past years, we have given a good shaking to our competitions. We're combining everything into a few single categories no matter whether it's oldschool or newschool, hardware hack or software masterpiece: The new competitions are called Realtime Demo, Realtime Size-Limited, Non-Realtime and Interactive. Read all about this new schema (and the voting mode coming with it) on our competitions page.

We'll finally have a decent barbecue at our event. We'll have plenty of outside space and we will give you a grill to heat your meat. There's absolutely no need to bring your own grill to the party. Also, there's not much need to bring your own meat (unless you're very hungry): Echtzeit, the organizers of the Demodays, give away a good piece of meat with every three-day entrance ticket (while supplies last) and you'll be able to buy more meat at our bar (also, while supplies last). This is our way to celebrate the 20st edition of Buenzli! You do absolutely not want to miss this!

After you had a fine piece of meat and a few drinks, you wonder where to sleep? We have sleeping space at the party place (it will be tight, though) and we made up a few special deals with hotels near by. Check out our hotels page. In the town, all hotels are in 10 to 15 minute walking distance to the party place, so you can go for any of them. Hurry up with the discounted rooms, we've got only a few.

At this Demodays/Buenzli, we're going to show a lot of demos. But we realized one thing: We need quality suggestions from a lot of different people with a lot of different tastes. This is why we ask you kindly to enter your personal suggestions. We have prepared a few topics/blocks of demos that we would like to show during the party and you could help us fill the blocks.
