"Pinhole" on film

A while ago somebody asked about pin"holes" exposed on film.
I have been thinking about this before, but never took the time to try it.
Now I had to do a print film and used the border of the page for some tests.
I only exposed some polaroid pictures until now, so I am not sure if the
sharpness actually equals a real hole.
But as far as I can tell from the first tests, it seems to work quite well.

The good thing about this technique is
a) it is very easy to make a perfectly clean hole of exact size
b) it is the only way to make holes of other shape, like stars (if you don't
have a laser)

The way to do it:
Use a vector graphics program (like corel draw and many others).
Draw a black square of 25*25 cm.
Put a white shape in the center of the square, using a size of 1 mm. (I used
one dot and two different stars from the "wingdings" font)
Combine the two objects and reduce the whole thing to 2.5*2.5 cm.
This way you can be sure that the "hole" will be 0.1cm .
(If you need other sizes, it should be not too difficult to calculate)
Then you can duplicate the object as often as the size of the page allows
it.
Save it as print file and send it to your service bureau.

Unfortunately, I don't have much time at the moment for playing around with
them, but if somebody else would like to try it:
I have made enough "filmholes", so that the first 10 people who send me
their snail-address can get a set of them.

I would like to see the results!

PS: some of my pinhole photographs can be seen on www.chwirsing.de (made
with a zero2000, not the "filmholes" yet)
