@Harry C Wilson Nah, I take you curse on the chin and curse your rubber ducky with the fear of drowning in response. -
Jerehmia 29th May 2023@BlueLobsterTPT They're 6-segment displays. 5-segment displays look a bit silly because they inevitably have one or two numbers that either have too few or exta lines, with 6-segment displays it's just the zero that either looks too small or is asymmetric.
