What is, and What is Possible comprises four of his projects, i.e. Live Forever (2011), Stopped Clock  (2010), Revolution (2010) and Empty Stages (2003−ongoing), a collaboration with Hugo Glendinning. All of these projects are permeated by extraordinary relativity, which amounts to a dialogue between the material and the non-material.

Empty Stages, a photographic project underway since 2003, already involves over 100 photographs. In them, Etchells and his long-time collaborator Glendinning catalogue empty stages all over the world and in the most diverse contexts, including pubs, conference halls, amateur theatres, churches, urban theatres, workers’ clubs and hotels… It is exactly through the images of these temporarily deserted venues that the artists explore the phenomenon of the stage as a space of uncertainty and expectation, inviting the viewer to create his or her own idea of what has occurred or might still occur on them.

The other projects shown in the exhibition are designed to open up similar imaginative spheres. Along with his neon installation Revolution, which will be presented in the gallery, Etchells as a visual artist is included in this year’s Lighting Guerrilla with his ambiguous and playful neon phrases executed in bright colours, which is also shown in the "exterior" urban space. In the very centre of Slovenia’s capital they invite – or even urge – passers-by to react, either mentally, verbally, emotionally or kinetically … just like Etchells’s stage masterpieces.

As part of Etchells’s exhibition What Is, and What Is Possible there is also a small but real empty stage which will be filled according to their taste by Tim’s guests, among them a philosopher, a conceptual artist, and a promising performer. Apart from this, the stage will be used for the many other festival & exhibition events.
