I like it! Reminds me of Chris Niemann and the 1st episode in the Abstract series on Netflix — http://www.christophniemann.com/portfolio/abstractsunday/. I love his play on dimensions and everyday objects with sketching.
I like that intersection between enjoyment and marketability. It helped me reflect about why some of my side-projects were more successful than others. Thanks for that.
Recently, I discussed some of my side-projects and also explained my motivations for working on them — https://medium.com/@cgbhatia/one-for-them-and-one-for-us-part-01-b14aaa0957c0
Great content! This goes back to the idea of design never being complete. Being continuously iterative and growing with users can create opportunities where users are surprised and delighted even over time. I have been trying to do that on my portfolio website as well by making updates that can create opportunities for delight.
