Since the launch of the New Builders light board video series, we've received a lot of questions about exactly how we did it.

We decided to pull back the curtain and answer your questions about this successful series.

1. No, the speaker doesn’t write backwards. We flip the video horizontally in post-production.(see the photo of our set below)

2. No, there are no mirrors involved - it does look backwards, but ... (see #1)

3. We just use standard fluorescent markers. No lasers or light-up pens, sorry.

4. The light comes from LEDs in a strip around the edge of the glass within the frame.

Below is a behind-the-scenes photo of one of our speakers, Sai Vennam, on set in our  Austin, TX studio. 

We hope this answers your questions. If you have more, please comment below.
