atomictom / background-changer.js
Created April 20, 2015 17:26
/** Instructions:
*
* This script is meant to make it easy to test out various transparent
* textures from transparenttextures.com. I used Python + Requests +
* BeautifulSoup to generate the list of textures. A similar method could be
* used to try out backgrounds from a site such as subtlepatterns.com (in
* fact, these names probably work with that site, if you change the source
* variable).
*
* In order to see the currect texture's name, include this snippet directly

* A demonstration of the lack of multiple dispatch in Java
* Notice how there is late dispatch on the object which owns "multi"
*
* (i.e the 'c' in `c.multi(o)`)
* But there is only static dispatch on method arguments
* (i.e the 'o' in `c.multi(o)`)
