Problem: Steven Spielberg:

His next directorial feature was the Raiders prequel Indiana Jones and the Temple of Doom. Teaming up once again with Lucas and Ford, the film was plagued with uncertainty for the material and script. This film and the Spielberg-produced Gremlins led to the creation of the PG-13 rating due to the high level of violence in films targeted at younger audiences. In spite of this, Temple of Doom is rated PG by the MPAA, even though it is the darkest and, possibly, most violent Indy film. Nonetheless, the film was still a huge blockbuster hit in 1984. It was on this project that Spielberg also met his future wife, actress Kate Capshaw.

In what year did Kate Capshaw start her acting career?

Problem: Light-emitting diode:

Digital-RGB LEDs are RGB LEDs that contain their own "smart" control electronics. In addition to power and ground, these provide connections for data-in, data-out, and sometimes a clock or strobe signal. These are connected in a daisy chain, with the data in of the first LED sourced by a microprocessor, which can control the brightness and color of each LED independently of the others. They are used where a combination of maximum control and minimum visible electronics are needed such as strings for Christmas and LED matrices. Some even have refresh rates in the kHz range, allowing for basic video applications.

What is one example of where non-Digital RGB LED lights are used?
