 The essential characteristics of the presented implementation are:
- * Efficiency of the reprogramming process - the entire process takes under 30 seconds, independent of the number of pieces
- * Visual detail - the displays used on the pieces are multicolored (4 colors), with a DPI of 210
+  * Efficiency of the reprogramming process - the entire process takes under 30 seconds, independent of the number of pieces
- * Spatial efficiency - for reprogramming, the pieces are placed in stacks of 7+ pieces (configurable via software), with the entire assembly usable on a small surface area
+  * Visual detail - the displays used on the pieces are multicolored (4 colors), with a DPI of 210
- * Autonomy and longevity - there are no batteries, and the electronic components do not wear out quickly

 Essentially, this is my attempt at trying to get the best of both worlds - the simplicity of a physical piece set with the software-driven freedom of general purpose displays.
