Animation movies have been a part of the demoscene since a long time. You might have a whole story line for a demo in your mind, but you're no programmer?

    • Max duration: 10 minutes
    • Voting categories: technical difficulty and creativity


    Video capture of an OHP Demo

As long as you're not using OHP-LCP screens, you can let your creativity flow and show off with your life performing of your best analouge demo.

      • We provide an OHP and you do the production for it
      • Max duration: 6 minutes

          4k Executable Graphics

          8 Ball by Westlicht

          Originally invented by Pro/Nuance, a long time Demodays organizer, this category had a good impact to the demoscene. Show the audience what awesome still graphics you can render just out of a 4k executable. Where are the Shader wizards? This competition is also known as 4k Procedural Graphics Competition.

            Music (tracked, streamed, chipped)

            Screenshot of Fasttracker IIScreenshot of Renoise

            Music has a long history in the demoscene and there's no proper demo without a soundtrack. Tracked music is traditionally made in a tracker using a lot of samples while for streamed music, you can go and use any technique or tool you want. Chipmusic speaks for itself, and while we have dedicated support for SID tunes, we also accept every other chip tune format as long as it's supplied as an MP3 for us to playback.

              Streamed, tracked and chip entries will be in ONE compo - if there are too many entries, we will preselect them.

              Rules for Tracked/Chip Music:

              • Allowed Formats: MOD, S3M, XM, SKM, IT, MT2, MTM, RNS & XRNS (Renoise), SID
              • No external VST-Plugins allowed (for Renoise: Standard player will be used)

              Rules for Streamed Music:

              • Your tune has to be MP3/OGG-encoded

              General Rules for the Music Compo:

              • Players: XMPlay, MadTracker, Renoise, Winamp (free available players)
              • Your audience wants to be able to dance to your music, so make it rock!
              • Max duration: 4 minutes
              • The tunes will be played on a standard soundcard, SID will be played on a C64
              • The format will be clearly shown on the big screen

                    • The topic will be announced at the party.
                    • You'll have enough time (about 24 hours) to contribute with your own fast made entry.

                    General Rules

                    The following rules apply to all competitions

                    • Every contributor may contribute once per competition.
                    • Entries to competitions have to be previously unreleased. This means: If it is already officially released (Scene.org, Pouet, your website, other parties…) the entry will be rejected.
                    • If a competition consists of less than 3 entries, we reserve the right to cancel it altogether or we will pool it together with another suitable competition. We will talk to you about it before any decisions are made so that you have the chance to withdraw your entry from the competition. You can set a preference when submitting an entry.
                    • If there are too many entries in a particular category, we reserve the right to preselect based on subjective impressions of an ad-hoc jury.
                    • Entries which violate Swiss law, heavy pornography, racism, etc. are not allowed and will be rejected and deleted without further notice.
                    • Make sure your entry does not violate any copyrights, license agreements, et al.
                    • Each entry will be released on scene.org and possibily other FTP sites, unless it was preselected/disqualified, or the competition was canceled.
                    • Voting is public. If we decide to hand out a jury prize again, this specific price will be given away by a jury, which will be formed at the party.
                    • The rules may be modified and/or extended by the staff.
                    • Keep in mind: We all want to see your releases. So if you are not sure if your production is violating a one of the rules, contact us in advance or at the party. We will find a solution, for sure.


                    We are able to record the following output formats, so make sure your hardware can output this: Composite-, S-Video-, Component- and HDMI connectors providing SD-formats 625i/50, 625p PAL and 525i/59.94, 525p NTSC, 480p or HD-formats 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25,1080p29.97, 1080p30, 720p50, 720p59.94 and 720p60.

                    So called «wild» entries used to be anything that didn't fit to any other category because it, for example, made use of «weird» hardware. With the change of our categories to be platform independant, your wild entry will for sure either fit to one of the realtime compos, to the interactive competition or to the non-realtime competition.

                    Feel free to contact us anytime with a short description of your production and we'll help you to decide which comeptition is the one that fits.

                    Remote entries

                    Can't make it to the party? No problem: remote entries can be submitted to participate in all of our competitions. Here are some additional rules for remote entries:

                    • Send your production to remotecompos@buenz.li before the 22nd of August 2014, 23:59 CET.
                    • Remote entries are being voted for just like normal entries but can’t win prizes.
                    • In case we receive too many entries for a competition, entries by visitors are shown/played while remote entries might get preselected. We will not spread your contribution in this case.


                    All the inputs will be scaled to fit a resolution of 720p (the projector's resolution, keeping the aspect ratio the same. Our video setup is completely digital. Your device needs one of the following outputs: HDMI, DVI, VGA, S-Video, YUV. If your device does not have a video output at all, we can pre-tape your competition entry using our professional video equipment. But make sure to announce that in advance, not 10 minutes before the compo starts! :-)


                    We run a professional PA system which is being used at the location for concerts and other events. The PA is equalized and compensates for room acoustics to a certain degree. Don't expect audiophile quality: Audio is analogue.
