Review on Eisco Acrylic Prism Equilateral Length by Ryan Bennett

I thought this would make a good birthday present for a family member after another family member saw one and commented on how interesting it was. And the birthday boy liked it. She placed it so that it caught the midday sun and projected the spectrum onto the wall. And the spectrum "magically" moves and changes (her choice of words) as the sun goes down. She says it reminds her of my love for her!
