Embodiments include an inflatable support structure enclosing a region fillable by a fluid at a positive pressure above an atmospheric pressure. A flexible screen is attached to the support structure, a region between the flexible screen and the support structure fillable by a fluid at a negative pressure below the atmospheric pressure that holds the flexible screen in a shape suitable for image projection. A method according to embodiments includes inflating an inflatable support structure with a fluid at a positive pressure above an atmospheric pressure and removing fluid from a region between the support structure and a flexible screen attached to the support structure to hold the flexible screen in a shape suitable for image projection with the fluid at the negative pressure below the atmospheric pressure between the flexible screen and the support structure.
