Pardon for the intrusion. I was wondering if you ever feature interesting and novel pi products on your blog? I figured I’d check in with you via email rather than cluttering up your blog with a comment.

Specifically, my company offers a Digits of Pi poster with almost 6 million digits. Millions more digits than other posters on the market. It’s a printing marvel and also a tribute to the computation of pi to almost 6 million digits.

What also makes it different is that a magnifier is required to view the pi digits, which makes it really fun and interactive. It’s a tool to spark a student’s interest in pi by having them search for repeating patterns of the digits in the poster.
