These are addressable 1-meter-long 5V RGB LED strips that come packed with 60 APA102Cs. APA102s can be controlled with a standard SPI interface, and they have an extremely high PWM frequency. There is access to each APA102 LED, and each strip length can be easily modified. You will be able to control each LED RGB individually.
The Teensy Prop Shield has 5V buffers meant to send data to Dotstar or APA102 type addressable LEDs.
