My wife and I were watching Lighter & Princess (点燃我，温暖你). In episode 5, a smart programmer completed a heart animation as part of a programming test in a university course. Everyone of his classmates had a mediocre and simplistic implementation.
My wife challenged me to do the same. I could have done this with SVG and Javascript, but I took the opportunity to learn more Python and Qt. The latter I have not used at all and was always curious how well it worked with Python. I decided to use the PyQt package instead of the PySide package.
I hacked this together today resulting in this rendition:
The PyQt implementation worked really well across Windows, Mac, and Ubuntu Linux. I suppose the Javascript and SVG would have done the same, but I learned something new in this case.
