In the past few years, we have covered plenty of unique chessboards here. The MegaChess 25 Inch LED Chess Set is also worth a look. It is a giant LED chessboard with illuminated pieces that you can use to play outside at night. You get two light color choices and can turn on each piece individually.
These large high-density polyethylene (HDPE) recycled plastic chess pieces can be stored outside without maintenance or worrying about any fading. The bad news? Something like this doesn’t come cheap.
