 ### Other Projects That Could Depend On This
 - do the problems online/on computer
 - a website to serve these up and let people use them for free
   - a web API that serves it, so people can do that programmatically
+  - a snail mail service?
+    - https://developers.lulu.com/price-calculator
+  - if there's going to be exercises in the browser,
+    - parseInt('0101', 2)
+  - maybe re-implement in Javascript so all computation and rendering is done on the client
