    Brian, thank you so much for featuring my design on your website and Scott, thank you so much for the excellent article!

    If any of your readers are in Northern Colorado, I'ld like to share that the Rainbow Apparatus and several of my other shadow casting lamps will be exhibited at Artworks Loveland starting this Friday and through August 28th as part of their Creator/Maker/Innovator exhibit.
