Computing with Planar Toppling Domino Arrangements Stevens, W.M. (2011)
Book chapter, pages 224-233 in 'Unconventional Computation (2011) - Lecture Notes in Computer Science', Springer Berlin / Heidelberg, DOI:10.1007/978-3-642-21341-0_25

Shows that any Boolean function can be implemented using a planar arrangements of dominoes - i.e. with no bridges for crossing one line of dominoes over another.
