Bi-Zen-Tennial Celebration!

In the world of Zentangle, Laura Harms (aka the Diva) has been hosting a weekly challenge on her blog for 200 weeks. This week marks the Bi-Zen-Tennial challenge which also inspired me to return to regular blogging here on Tangled Planet.
I've chosen one of my favorite go-to tangles, 'Phicops'--a pattern designed by Laura's husband Brad for the Diva's challenge #101 . I like this tangle for the left-right-left (or, right-left-right) motion of the strokes in each section. Laura is hoping for 200 submissions for this week's challenge. If you haven't already, please give it a try!
