I think your best bet would be one of those small plastic refraction lenses
used to make homemade spectrometers out of. I remember making one in college
astronomy class. The lens was like a 1 1/2" square and only tater chip thick.
I think they used to come from Edmund Scientific. Practically no weight at
all.

See ya,

Hi Richard, thanks for your reply,

before I spend about a zillion years downloading with my 28.8K modem I'd
like to know if there's a print function in this program. From the site
it seems (though it doesn't say anywhere) that there is no way of
hardcopying using the program.

Thankyou once again and cheers,

Thomas
