Give me your mailing address, Marilyn. We here is Iowa
would be delighted to ship snow to you. We already have too much and
are expecting too much more. I want spring!
It was good to hear that Andy is still functioning. We are suffering
in his absence. I did post another image to the Flickr site.

Good hearing from you, Andy. How are you? What is the
weather like where you are? My husband just got the lawnmower out a
few days ago, so he's probably wishing we had some snow {:->

I hope the question was about FRONT
projection and not rear projection. I better check!
They are retroreflective - much more efficient reflectors than normal
projection screens. Similar to material used for highway signs and
reflective tape used on various clothing apparel, etc. ~ andy
