"Transitions" by Marci Baker was created using blocks designed by her "3-D Magic!" co-author Sara Nephew.

For Transitions, Marci worked with new blocks and sizes that her 3-D Magic! co-author Sara Nephew designed. The transitions of the title occur as the pink blocks at the top become the blue ones on the bottom, using light, medium, and dark variations of the different fabrics to create the 3-D vision. She and Sara call the top blocks "Peek-A-Boo", followed by a traditional block, and then the bottom ones are "I See You" blocks.
