&pureforms
With the jam project coming to a close, we created the first PureForms app and what may very well be the worst reinvention of a wheel ever: A color picker that only works in increments of 16 and doesn't even give you the RGB value of the color you've created. But it does show you pretty tool tips, badger you about closing it, and take up only ~150 LOC. Be sure to check out PureForms in its entirety at https://github.com/errorsuccessdev/PureForms. I've also written up an overview of what this project is and what it's for over at https://handmade.network/p/592/pureforms/. I plan to continue working on this library post-jam, so if easy Win32 GUI dev is appealing to you, keep an eye out!
