Announcing X in a Box & Array 101

Posted in Uncategorized on May 28, 2020 by Brit Cruise

In March 2020, I launched a new company (X in a Box – with my colleagues Tony DeRose and Elyse Klaidman. Our idea was to take what we’ve accomplished with Pixar & Imagineering in a Box and expand on it in various ways. Here is a teaser of what we do:


We’ve been unexpectedly inundated with opportunities because of the dramatic shift to online learning as a result of the pandemic. Continue reading

The Beauty of Neural Networks

Posted in Uncategorized on November 15, 2019 by Brit Cruise

I’m thrilled to finally post part 3 in my Deep Learning series, it covers the first 80 years of neural network research and was one of the more difficult scripts & visualizations I’ve ever worked on. It pulls together many years of thinking about this subject:

Making “Imagineering in a Box”

Posted in Uncategorized on July 30, 2019 by Brit Cruise

Screen Shot 2019-07-30 at 12.03.00 PMToday I’m happy to announce we are finally launching Imagineering in a Box on Khan Academy from my team behind Pixar in a Box + some new partners at Walt Disney Imagineering. Here is a five min overview of the project:

A Brief History

When I was 12, I was so curious to find out how one could become an Imagineer. I wanted to learn about all the cool work going on behind the scenes of a theme park.

Been hard at work at a seven part series on AI. I’ll most more details soon. For now:


What I made with IEEE in 2018

Posted in Uncategorized on December 12, 2018 by Brit Cruise

This year I produced two videos with my friends at IEEE (Information Theory Society) which cover two highly influential academic papers from the 20th Century. What’s really exciting about these videos is we had the original authors of the papers review the script during development (Abraham Lempel and Robert Gallager). On average we spent about 4 months writing & iterating on each script until we had something that is clear and correct.

Here they are:

Lempel-Ziv compression – One of the most influential compression algorithms of the 20th Century:

LDPC codes – One of the most versatile and widely applicable error correction codes which was about 40 years ahead of its time:


In 2019 I will continue this project with IEEE.

What is Bitcoin?

Posted in Uncategorized on May 28, 2018 by Brit Cruise

I spent a long time thinking about a way to explain the what/why/how’s of Bitcoin to general audiences (my Mom) in a way that doesn’t frustrate Engineers (no hand waving). I feel that all existing Bitcoin videos contain jargon that scares away the typical viewer. In this video I made a point to avoid using a single word that might confuse people. I don’t know if I succeeded but I tried my very very best…


Please share this video with anyone who still doesn’t “get it” – as it might fill in some gaps.



Art of the Problem & IEEE join forces with “The Information Age”

Posted in Uncategorized on November 5, 2017 by Brit Cruise

This year marked the beginning of a long term collaboration with IEEE Information Theory Society. The goal of our ‘Information Age’ series is to produce short videos which bring to life the most impactful ideas from Information Theory and show how they play a role in our lives today. The first two pilot videos we produced in 2017 were on Network Coding and Space-Time codes. In 2018 we’ll be exploring source coding, channel coding, quantum information theory and security. Below are the 2017 pilot videos. I’ve enjoyed working with Matthieu Bloch, Michelle Effros, Christina Fragouli & Suhas Diggavi on this project.

Space-Time codes (multi-input multi-output networks):
