  • At this stage, you would get extra points if you could just hit the moon; regardless of speed.

  • It would not be much different than the multicolored LED matrices (I concede they have separate anodes). Those are generally operated via PWM (ie MAX72xx). You have a bit more wiggle room in Vf with PWM.
    Also, with 8 pins, you could drive two of these with a single MAX72xx.

  • They could have easily multiplexed the LEDs, 4 sets of 4 would have resulted in 8 pins total.

No public wish lists :(
