IBM Technology

Since the launch of our lightboard videos, 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 from our Austin, TX studio.  

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

I had really liked the idea that he had the special ability of writing backwards.

simple trick but very effective - this would be cool to do a DIY at home setup for live streaming - team/live archtecture sessions would be so much more interactive

Definitely came here for this explanation after watching Sai's Terraform video and thinking his writing flowed wayy too naturally to be written backwards to what he was seeing so it showed up forwards for us! 🤯

So, for just more than an hour now, I have watched different videos (of different cloud concepts) that I was kind of not updated on. Really liked the brief explanations and still watching more. Kudos to IBM Cloud for this (but not for kind-of killing the CentOS)
