Abstract Laser

Mrs W invested in a couple of prisms a little while ago, and although we have tried a few things without great success, today we thought we should get a laser pen and try that.  Then I remembered that MANY years ago I bought a laser level when we first moved in to help with alterations/decoration etc.  It got used once in anger to set out the village allotments after we rescued them from the then Parish Council.
 
So this is a little basic experiment using a laser and prisms. For the techies the laser is to the right and pointing slightly down to the bottom of the upright prism.

Thanks to Ingeborg for hosting Abstract Thursday.

ps - this is a must to view in 'large'
