Toys and tools to try

As part of the 30 Days of Lists, one was a List of toys and tools you'd like to try. I found this one on Flipboard the other day so for an Instagram lover, I thought this will be a cool printer to have. I enjoy the polaroid which prints 3x4 that my honey gave me for Christmas. However, it'd be cool to print square photos of my instagram. Hope these guys will make it to mass production someday soon! What are the toys you would want to try?
