It is no longer the world's biggest! The world's biggest is by Dominodaytv 30x30:

It took me 3 attempts (about 27 hours of building) before completing this pyramid, which took an additional 17 hours to complete over several days.

Sadly, I didn't learn from my 25x25 pyramid and this one needed help getting started too! :sigh:

I have a few extra near accidents and stuff from this project that I've put on my other channel:
