Hi I'm interested..How about some pics of the projector itself..? thanks for sharing!

depends, lcd is the most expensive part of this project. I'm using a 15.6" Samsung 633NW. Cost will be apprx 15-20k. Compared to commercial projectors which cost a lot and replacement bulbs are very expensive. For this project the bulb only cost 700 pesos and can be bought on local electrical or hardware stores.

I will try to post some pics of my PJ. It's not pretty and it's big, if size is an issue you can always make a vertical setup which could save you space by using a mirror to bend the light and project an image.
It is possible to use a smaller lcd to make your projector smaller.
