Okay, so I am currently OBSESSED with this Kikkerland rainbow maker. I bought it last month at Hammertown in Rhinebeck...and it has made every morning since then magical.
It's a solar powered prism that you stick on a window....and it turns when the sun is shining. Pretty genius! Right? Ours is in the bedroom...which has east facing windows and fantastic light all morning. So now we get to wake up to a parade of rainbows every day. Love love love.
