Hi
Coming from a flash-processing-unity and open frameworks background my primary focus is using Houdini as a creative coding platform.
I'm familiar with Entagma's tutorials. In the world of flash I was always inspired and learned from Jared Tarbell's work

Can anyone suggest other Houdini tutorials with a focus on ‘creative’ coding?

Thank you for the links!

The best match I know is:

No tutorials, but example codes and files.

Stassius tutorials are also about creating abstract shapes sometimes:
