This is a simple test app I wanted to build and test out by submitting to the 21.co Marketplace.
First open the command line in your 21 Computer:
$ git clone http://github.com/cponeill/21RandomFactApp.git
$ cd 21RandomFactApp/
Run the server:
$ python3 server.py
Open another terminal, change directory into 21RandomFactApp/static:
$ sudo pip3 install pyfiglet
$ python3 client.py
You should now see a random fact in your terminal. Oh the Joy!
