When you’re putting on an interdimensional art show you need somewhere to host your party. Places, spaces, architecture, planes of existence – where will you take us!?

• Create a 3D model of an imaginative and functional interdimensional art gallery space – you’ll need to build places to put the art, but also space for your guests to mingle.
