I was introduced to Kapla, "the construction plank for big and small" this sunny Sunday morning and delighted in the simplicity and precision of this popular toy (only regretting the limited size of the set). Conceived by Tom van der Bruggen in 1988 to build a model of his "dream castle", he developed the little planks into a toy and named it after his native Dutch "KAbouter PLAnkjes" (gnome planks). Using sustainable pine and non toxic colours, Kapla has been environmentally conscious since inception. The perfectly uniform nature and proportion (1:3:15) of the shapes allow builders of any age to create massive and complicated structures using no supports or adhesives. See the video below for an example of impressive Kapla work.
