I've put together - bitcat - a little sinatra web app
(e.g.bitcat/app.rb ) in ruby packaged up as a command line tool
that lets you browse your digital bits(s) eg. crypto kitties and
friends unchained (offline) using a single-file SQLite database eg.
Note: Bitcat includes the gene / genome reader in base32/kai
notation from copycats  - another ruby library for (crypto) cats /
kitties - and more.
Happy collecting. Happy gene mixing. Happy hacking with ruby. The
future is meow. Cheers.
