I, too, have my flings with the triangle.
My July 11, 2014 – July 23, 2014 focus was on what I call “The Leaky Triangle”.
I didn’t develop it further but it was an intense flurry of study and output for 12 days, most I put here:
“The right equipment can turn a concrete wall into a floor.” that was a favorite realization. I had a bunch and I tried to make them ‘catchy’ so I wouldn’t forget.
