I went to the 2015 NY Toy Fair (tweets and pictures at https://storify.com/scottnicholson/my-day-at-the-ny-toy-fair) and found one product that really got me excited.
It's called The Extraordinaires Design Studio, created by the same group who made Rory's Story Cubes. It's all about learning how to make a design with a user in mind, which is a valuable lesson for anyone who creates things. I'm teaching a course on Experience Design this semester, and I was amused how they have taken the concepts I'm teaching in that course and turned it into something for kids and families to explore.
