This is one of the coolest ideas I've ever seen on DA or etsy for that matter. Imagine a natural themed room with shelves covered in these with a wire linking then together like Christmas lights. It would be so relaxing to be in a room like that.
oh man it would be a lot of work, but I think it could also be very lovely. Just have nice wooden shelves lined with them, have a nice indoor water fountain, maybe some potted plants. It could be a meditation room. Or you know you could just use them as night lights. I would buy those for sure.
