“Tim”, also known as “Jediairmech” is not just demonstrating a memory feat, but teaching a memorization course. In these videos, you'll learn how to remember numbers using the Peg System. In the Mental Gym's Memory Basics section, you can learn more about the Peg System, as well as other memory techniques.

From the response to the first videos, it looks as though he is planning to make more Memorization Course videos, so I'll keep this playlist updated the new lessons are posted.
