Solar powered double panel LCD game (it has two LCDs on top of each other to enable much more impressive scene changes and possibly 3D like effects). Neat design, I know of these Double-panel games: Airport Panic, Frankenstein (or Mr. Franken), Hikyo Amazon (or Amazone), Terror House (or Akuryo No Yakata), Zaxxon. All but Zaxxon are solar powered games.
