this is a project to create postcards for mailing.
mostly this is a wishlist kind of thing, but as a stake in the ground here's something like a structure for it.
target language is Python.
the main application is the command line app:
postcard --to mom --photo cute-kids.jpg --message "they get so big so fast! love ed"
which should generate a job at some print service to send a postcard in the mail with that text on it to that address.
which suggests several helper/helpful requirements:
tools for address management, manipulation, databases etc, so that you can say "--to mom" instead of some UID or full address.
tools for managing and maintaining photographs and other art so that you can say "--photo cute-kids.jpg" and it will do the right thing.
should include some use of "sips" for image resizing on mac, plus whatever the linux alternative is.
tools for turning text into lovely text for the text side of the screen, to support the "--message" option.
the printer side of this world, including job queuing and other outsourced printing options
lob does postcards, $0.70 each (2015 prices).
