Hi @yufengz welcome to the forum!
Great to see PCD coming back to the MIT Media Lab for the 25th anniversary of Processing. Seems very fitting since Processing started there.
I’ve merged PR #65, and PCD @ Boston/Cambridge is now live on the PCD map.

Feel free to post on the main thread if you have any questions or feedback. I will be checking regularly. I’m here to help 
Best,
