Sir, i was very much delighted to find your website on the net while searching for pin hole images.
Actually i was trying to find solution to a different phenomenon .
" Take a mirror outdoors when sun is in the sky.Observe the reflection of the sun onto a wall. If the wall is nearby we see the shape of the mirror and if the wall is far away we see the shape of sun."

I realise that this is similar to a pin-hole image, execpt that the image is on the opposite side.Because a mirror is equivalent to a hole, both differing only in the side where image is formed.

I would be happy if the java applet is made so as to vary the distance of the image plane from pin-hole and also if along with the letter 'F', there is also object like sun(a round ball).

Eagerly waiting for your response...Thank you.
