Instead of the n-th Tutorial website, I would love a list of worthwhile projects one can build with increasingly tougher level of difficulty, start with MNIST and move up. You don't have to hand-hold me by providing a sandbox, but suggested frameworks are welcome.

Ending the list with a couple of research/unsolved problems is perfect.

To me, this is the perfect way to learn, almost like feel your way blind in a cave and reaching its extents.
