I have a couple of small ones, but one that stands out is actually fairly recent.

It was an independent project, more for practice than anything, but it involved fetching daily horoscopes from an RSS feed and showing it to the user upon request. I first just made it as a command line program,using some new modules I hadn't used before, and seeing everything work smoothly and neatly printed out made me super excited.

Not too long ago I even made a proper GUI for it using Tkinter, which also works nicely. :) Nothing so far has beaten that first excitement upon finishing the command line one, though.
