Pretty cool idea but unless you knock the focus off on the enlarger, it's going to look like shit. If you consider photo paper to be around 300dpi then your 400x480 cheap ass smartphone display is going to be pretty obvious.

So blurry or pixelated. Your choice :)

N.B this might be desirable from an artistic point of view though.

The iPhone 4S (so, the one in all the demo photos) has a screen resolution of 640×960 at 326 ppi, and the Enfojer uses plastic "toy camera" lenses similar to the ones in Lomography cameras, so the results are always going to be slightly blurred.

Is it really that bad? Web designers have been taking pictures of their screens for years. You still have the original 'negative' if you need the extra image quality.

Edit: There should really be a couple sample images on the project page.

Yes it's really that bad. Us print people have been holding our noses with web screen shots for years. They really look bad when printed at 300dpi on paper. I would have to see the results with the even finer chemical grain of photo paper, but I would expect it to look even worse.
