The one we find most interesting is a PWM based dimming hack he pulled off with an Arduino board and a FET. The bulbs are designed to be dimmable through the 12V supply that feeds the light fixture.

Your robot army, controlled by Arduino and Bluetooth Open-source hardware project shrinks Arduino, adds wireless, creates awesome.

For use in automotive display backlights, automotive lighting applications and LCD backlights, Maxim has posted detail of the MAX16838B which it says is the only-available 2-String HB LED driver ...

Atmel’s multi-string LED driver family offers efficiency optimizer (EO) technology, flexible dimming options, scalability across a wide range of power levels, user programmability, and promises ...

Current settings are typically accurate to 2%, while typical matching between LED strings is 0.8%. An internal pwm generator is included for dimming, with two resistors setting frequency and ratio, or ...

Mini-LED backlighting and full-array local dimming are different things, and they actually work together. In fact, it is very rare to find a mini-LED TV that does not also have local dimming.
