Raymond Camden shares his experience creating a LEGO-themed screensaver for Mac using data from Rebrickable. He describes the process of filtering LEGO sets based on their buildability and how Cursor assisted him in developing the project despite his lack of OSX development knowledge. The screensaver features random LEGO sets, displaying their names, years, piece counts, and images. He provides a link to the GitHub repository for users to check out and notes a requirement for whitelisting the app due to not having a developer's license.
