Glass Onion is an unrealised project by Brian Clarke for a movable, itinerant pavilion entirely made of glass and designed to serve as a Beatles experience. Conceived in 2008, the project was inspired by the Beatles song Glass Onion.

Clarke’s project survives in the form of a model and additional designs. It envisioned a sinuous glass structure adorned with colourful, large-scale ‘splashes’ alongside photographic portraits of The Beatles on glass.
