Tell me a bit about your style and where this room is in your home. It looks like there's a window on the right hand side - is there a nice view to look out and focus on or is this white wall the main focal point of the room? Are you able to paint the walls? If you can tell me a little more and maybe give an idea about the dimensions of the room that would be great!

huh...some kind of projection? If you want to do something with texture for $5, apparently you can draw on a light bulb with a sharpie and get a cool effect. Never tried it.

Based on the information from the picture , lawn ( green patch ) can be seen adjacent to the wall, Vertical gardening can be done on the walls to create more playful green areas. Seems you have planned seating area at the corner , these green walls will add aesthetics to your seating area. Seeing the picture wall seems to have shade at the peak hours of sunshine so this vertical gardening will save lot on your maintenance and watering part.

Glass will be good if it can sustain air pressure
