UPDATE: APPLY FOR ART CUBES OPEN. APPLY FOR PAVILIONS CLOSED:
The most easy way is to apply via the Contact form or to send an email to info (at) 1biennale.com ~ everything you forward goes to “the web/gridmaster” ~ see Imprint which is a legal need for websites hosted in the European Union.
In opensim worlds you search for Biennale [Digitale] at Metropolis grid [hypergrid.org] and contact one of the land owners or group officers you find listed on the info plate.
In Second Life you contact Art Blue, Art Eames, JulietteSurrealdreaming Resident, Meshhuman Resident.
What you create – Pavilion or Cubes – you have to hand over to the Biennale gridmaster as a dae [Mesh] file – including textures – or upload it in the Biennale grid which is co-hosted in major grids like Metropolis. All IP rights have to be on you. You are not allowed to use objects you don’t have full rights on them. If you are an artist in Second Life you can work there in a sandbox provided to create a draft.
There is a notecard with TOS provided you have to agree based on virtual or facebook name ~ if you like you get a confirmation letter with your real name.
Most artists might be interested in creating a Cube.
