Its always great to see Oblique Strategies pop up on hn.

I was exposed to Oblique Strategies early on in my career and, whenever I got 'stuck' on a task, I would look at them like oracle cards to get my mind moving.

At the time, you couldn't buy the cards directly as they were out of print. One of my fondest gifts was my wife making me a set of custom index cards for each one. Its still sitting on my desk and used today.

Love it!
