projector project

There are a lot of news about how small the coming projector will be and commercial products have been produced and seen in fairs. Palm size, pocket size, pico size... even a phone can have a projector built-in. What for? to watch clips, games, file display and small group presentation etc. But I have another idea which I won't consider when project size is large and burning hot: Use it as an lighing object. Thanks to the ultra bright LED, these pocket size projector is so instant and cool with low power discipation. Now I can put it to illuminate a small corner with water wave pattern, moving shadow just like a big show room. Many idea is poping up now and what I need is to buy a good pocket projector with at least 500 lumens, 40 inch.
