Kind of off-topic, but "you'll be reminded of each regular expression every time you look at your laptop" reminded me of something:

Does anyone know of a good open-source (or just free to use) flash-cards app? I want to be able to download a bunch of images and create a deck from those images. The front of the card would be an image and the back would be a text description, all created by me. If the decks could be created from a file such as csv or json, it would be great, so I could automate the process of downloading the images and creating the descriptions.
