Which devs do you follow because they make loads of neat, imaginative projects?

I really like seeing what Frank Krueger has been up to https://github.com/praeclarum - aside from his GitHub projects (ooui was a cool experiment), he already made a few nifty ipad apps https://apps.apple.com/us/developer/krueger-systems-inc/id299293363?see-all=i-phonei-pad-apps e.g. Calca a cross between a capital, and c# ide called Continuous (which was a completely mad undertaking)
