Originally we planned to use black and white displays in Optimus Maximus keys. Pictured: studio senior engineer Maxim Pavlukhin showing demo circuit board with black and white LCD with 32 by 32 pixels resolution. Later on, we’ve changed out mind and Optimus Maximus went into production with full-color OLED displays with 48 by 48 resolution; black and white version went directly to archives.
