Everything you need to turn any blank wall into an atmosphere machine. Rain on glass, neon city lights, snowy mountain views -- all from a cheap mini projector and a free YouTube video.
It is dead simple. You point a mini projector at a blank wall, play a looping ambience video -- rain on glass, snow falling outside a cabin, a neon-lit Tokyo street -- and your room transforms. The projection looks and feels like a real window. Your brain fills in the rest. Add a candle and a cup of tea and you have got yourself an evening.
The whole thing went viral on TikTok when people started showing their boring rental flats completely transformed for the cost of a cheap projector and a free YouTube video. No drilling, no landlord drama, no skill required. You can have it running tonight for under fifty quid.
It works because of contrast. In a dimmed room, a projected window scene is bright enough to look genuinely real. The gentle movement of rain droplets or drifting snow makes it feel alive. It is not about watching something -- it is about changing the atmosphere of where you are. People use it for relaxation, focus, sleep, game nights, parties, and just making their space feel less like a box. We have a full setup guide if you want all the details, but this page gives you the quick version.
Good news: the shopping list is short. You probably already have half of it.
Any budget mini projector works. You do not need 4K or smart features. A basic one from Amazon for forty to eighty quid does the job brilliantly in a dark room.

No. A blank wall is actually better for this. Projector screens are designed for watching films with sharp detail. For ambience, a wall gives a softer, more natural look that resembles a real window. White or light-coloured walls work best. Read our no-screen guide for full details.
Budget projectors need a dark room to look their best, so they shine after sunset. If you want daytime use, you will need either blackout curtains or a brighter projector (300+ lumens). Most people use this as an evening or nighttime thing and it works perfectly.
Not at all. A projector is just light -- there is no heat, no contact, nothing touching the wall. You can project onto any surface without any risk of damage. It is completely renter-friendly.
Ambience videos on YouTube -- long, looping scenes designed to run for hours. Popular choices include rain on a window, snowy cabin views, Tokyo neon streets at night, cosy fireplace scenes, and forest views. There are thousands of free options. We have a curated list of the best 50+.
Mini projectors have small fans that produce a gentle hum -- roughly the same volume as a laptop. Most people find the ambient sound from the video (rain, nature sounds) masks the fan noise completely. It will not disturb anyone in the next room.
