Today I played around with my module for the PWTC Handbook in InDesign. This is what I came up with: PWTC Courses Module.
I got inspiration for this design from Richard T. Schaefer’s 7th edition textbook: Sociology, A Brief Introduction. It’s really a beautiful text book. Here’s a link it on Amazon.
You’ve achieved good balance with your distribution of the green here — the one thing I would say is that it requires a little effort for me to match up the projects with their corresponding courses. the slight overlap of bubbles and and horizontal alignment helps, but the vertical alignment (of green bubbles right above course titles) suggests a second possible grouping, so that the relationships are not immediately apparent.
