A couple of weeks ago I passed this storefront in Chinatown with an informal gallery of lenticular cards taped to the inside of the glass. I thought it was so cool and striking, just floating there, images shifting slightly as you passed. I even liked the scotch tape on the window. The door was locked so I peered inside the shop and saw just stacks of boxes and paper; I couldn't tell if it was a business that had closed for good, or if I was just looking in after-hours. I've been meaning to detour back to that block to see if the shop is open and I might acquire a set or two.
(You know what lenticular is even if you think you don't. Lenticular images have a plastic, stripey corduroy-like surface that makes a noise like 'zzzt zzzt zzzt' when you scratch it with your fingernails. The printed picture shifts depending on how you view it - you move it (or your head) back and forth to make the image change.)
