Ask HN: Suggest a deep-learning personal project?

After completion of deeplearning.ai courses I am looking for personal project to further improve my understanding of AI and have some fun.

I find applications of convolutional networks and sequence models especially interesting.

One of the ideas I have is to build a command-line tool to classify my photos (mark photos with people, nature, cities, similar photos, photos with bad light / focus, ...).

Could you suggest progression through such project with high-level tasks ordered by difficulty?

Other project suggestions are also welcome!
