Like LEGO? Got a Mac? Get My Screensaver

Good morning my fabulous readers. This will be a quick post as I just wanted to share something cool I built with Cursor over the past couple of days - a LEGO screensaver. I'm a huge fan of "show me something random from something I like" and have built multiple bots in that vein. I recently discovered Rebrickable's LEGO datasets which contains a CSV file of LEGO sets. The data looks like so:

set_num,name,year,theme_id,num_parts,img_url
0003977811-1,Ninjago: Book of Adventures,2022,761,1,https://cdn.rebrickable.com/media/sets/0003977811-1.jpg
001-1,Gears,1965,756,43,https://cdn.rebrickable.com/media/sets/001-1.jpg
0011-2,Town Mini-Figures,1979,67,12,https://cdn.rebrickable.com/media/sets/0011-2.jpg
0011-3,Castle 2 for 1 Bonus Offer,1987,199,0,https://cdn.rebrickable.com/media/sets/0011-3.jpg
0012-1,Space Mini-Figures,1979,143,12,https://cdn.rebrickable.com/media/sets/0012-1.jpg
0013-1,Space Mini-Figures,1979,143,12,https://cdn.rebrickable.com/media/sets/0013-1.jpg

I thought it would be cool to select a random set, show the year, name, number of pieces, and render the image as well. I gave this CSV to Cursor and started iterating on building a simple OSX screensaver. I had it filter out sets where the number of pieces was greater than or equal to 50 (typically "swag", non-buildable items) or with names that also appeared to be non-buildable things.

After that, I just let Cursor handle creating the project. I know nothing about OSX development, thankfully Cursor does. The only real issue I ran into was OSX aggressively caching the screensaver data which made updates a bit difficult. I think we (and by that I mean mostly Cursor, and some me) figured that out eventually.

Here's an example of how it looks:

Alright, so before I link you to the GitHub repo, a quick warning. I'm not paying Apple for a developer's license which means if you get the build, you'll need to run a one-time command in your terminal to whitelist the app.

Ok, with that out of the way, head over to the repo and check it out: https://github.com/cfjedimaster/lego-screensaver
