Default Image projection (noob question)

Hello people. This is my first post here. I'm new to lasers and know very little about them, but after browsing the forum I realize that this may likely become an obsession. I'm currently looking to purchase my first high power hand held pointer.

This may be a silly question, but any help/advice would be much appreciated.

I'm looking to make a portable laser image projector. The one showed on this site --
w w w . instructables.com/id/Laser-Image-Projector/ -- seems to do the job, but I'm wondering if it would be possible to make something even simpler and more portable, and use it on distances up to 50-100 meters. I suppose what I'm after is some sort of "laser grafitti torch" which utilizes a hand held laser pointer, a couple of lenses and a slide. The object is to project images on walls and slanted surfaces, so I'm thinking the slide holder must be adjustable, and the device could be attached to a tabletop tripod and put on the ground.

So, would it be possible/easy to display an image on a wall about 50-100 meters away by using a 200-300mW green laser, lenses and a slide?

(I realize, of course, that lasers must be used with caution.)

Many thanks.

BTW, after finding this clip, I realize the possibilities are endless.

I did something like that with an old projection tv lens and a slide taped behind the lens. worked very well with my dx 30 with the beam set to cover only the area of the image on the slide. Not sure about getting 50 or 100 meters out of it though.

I think the only way to do that (or at least the way I do it) is to upload the pics to a hosting service like http://imageshack.us then use : [ img ] http://url.for/image.jpg [ /img ] to embed them.

Thanks.

Does anyone have an opinion on whether this "300mw" is most likely crap quality, or whether it may be a good deal for this purpose?

cgi.ebay.com/BEST-FULL-POWER-300mW-GREEN-LASER-POINTER-532nm-GADGET_W0QQitemZ220233337181QQihZ012QQcategoryZ149 54QQrdZ1QQssPageNameZWD2VQQcmdZViewItem

Could I somehow combine two of those and get double output?

Read this thread to see how to combine up to 2 lasers of the same color.
