Some people argue against electronic fiction because the codex book offers a certain tangible manipulation. There is certainly something to be said for having a product in your hand, especially for children who learn spatial reasoning from their physical interaction with the world. David Merrill and Jeevan Kalinithi’s Siftables respond to this critique.
Siftables are programmable interactive blocks with screens. They respond to movement, orientation, and each other’s presence. They can also produce sound. As you can see in the demo, these blocks show amazing promise as a learning tool for kids, allowing them to practice their multiplication tables, as well as hone their authoring skills.
