Demodays 2011 are history and we had a very great time together with our visitors.

Demodays Discounts: Long-Distance and Students

Perhaps you have already seen that our entrance tickets in Euro are a bit more expensive than last year. While we are extremely sorry about the sucky conversion rate, we can't do much about it - except one thing: Showing our appreciation for visitors coming from far away we establish a long distance discount that applies for journey longer than 700km (as the crow flies). But that's not all yet, we also want to make it a bit more affordable for students to visit the Demodays. In consequence, we now have a students discount too.

Demodays Features: Ultrasyd and Restless Leg Syndrome

No demoparty without proper live acts: Demodays presents Ultrasyd (Friday evening) and Restless Leg Syndrome (Saturday), live on stage with pumping music for you to listen, enjoy and dance.

Ultrasyd, a retro-gaming lover and demoscene enthusiast since early 00s, started to compose chiptunes accidentally in 2009 when he decided to get himself a collection of old computers and video-game systems for the sake of nostalgia. Since then, he has been eating chip for breakfast, and now delivers a mix of entertaining beats, energetic basses and sweet melodies. He has a particular affection for the flavour of computers such as Amstrad CPC, Atari ST and C64, but doesn’t mind playing the Game Boy or composing electronic music with modern sequencers from time to time. Ultrasyd's gonna shake you on Friday, following the opening speech.

The guys from Restless Leg Syndrome are hardcore demoscene passivists and love to get active at the Demodays. The combo consists of Atombrot (who has previously played at Buenzli), Ox1d and Satelite Jack. For the Demodays gig, they might even go ahead and do psy remixes of famous demo soundtrack. They'll make you move on Saturday, between Demo-Night Part II and III.

Demodays Features: PixelInvaders

Pixels are invading the Demodays! Straight from Genoz/Vantage's secret labs, the PixelInvaders live installation will be present at the Demodays for you to play, watch and enjoy. Here's what the creator writes about his project: The «PixelInvaders» LED system consists of 3D RGB LED panels, which playback real-time generated video animations or simple color change. Multiple PixelInvaders panel can be connected with each other to form a panel of any size. The panels are based on the latest LED technology - besides low heat dissipation and long life a panel may illuminate an entire room - and consume less energy than a standard light bulb! Read more about this at

At Demodays, we gonna have a two-panel installation running all three days. This and other Demodays features are found on our Features Page.

Demodays Competitions: All New Categories

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.

Demodays Features: Barbecue and Accomodations

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.

Help us using the Suggest-A-Demo-Tron-X 2000

Pick your favourite demos for a certain category, add title and group, a link to the demo and your name (so that we can properly credit you) and hit save.

We're sure you can add one more :-) If you have a suggestion for another category, or if you want to prepare a special show on your own, that's awesome. Contact us about it!

Last Minute News

We are at the party place, building up the site for you. This also brings a few news items and changes for those that are planning to visit us this weekend.

First of all, there’s still the same car detour as last year (which means, that our travelling guide is a bit wrong in the end). Generally, you can always fillow the direction to "Museum" or "Kirchgemeindehaus", the street will lead you along the Buenzli location. Check this map for a bird’s view on the detour. In case of troubles and you feeling lost, just call our hotline.

Further, we have a bit of a delicate situation here, since the rest of the location building is booked, too. We kindly ask you to follow the special rule tweaks we have to apply (see more at the party place, slides). Thank you!

Last Buenzli at current Location?

Are you still unsure whether to come to Buenzli or not? If so, the following information might make you come: This might very well be the last Buenzli at the current location.

Twice the Fun: Combined Ticket

Evoke might be one week after Buenzli this year, but this doesn’t stop us from giving you twice the fun for not quite twice the price: If you plan to go to Buenzli as well as Evoke, you should buy the infamous "Combined Ticket". For only 65 Euros (instead of 70) you’ll be able to enjoy the compos of Evoke and Buenzli back to back.

So, if you are man enough to try this, mention that you would like to buy a combined ticket at the Buenzli infodesk and have your cash ready. One week later, at the Evoke infodesk you show your Buenzli bracelet and the ticket and you’re in. That’s it!

If you were not yet planning to go to Buenzli and Evoke, isn’t this reason enough to think it over?!
