Kaleidoscope is a big, colorful creative space with wacky decorations and ample art supplies. This is a project of Hallmark Cards, which is located in the same building, so a lot of the supplies are interestingly shaped scraps from greeting card production. One of the highlights is making your own small jigsaw puzzle with the on-site press. Best of all - it's free. Visiting requires some pre-planning and visitors only get a limited time in the space, but it's a great way to spend an hour when visiting Kansas City's Crown Center.
