For simple javascript animations there is always a trade off between code size and visual effects. Recently I was trying to add some visual pizzazz to hour weather but didn’t want to incur the overhead of JQuery UI. What I was looking for was just a simple bounce effect on some moving objects. A lighter weight alternative that I considered was JQuery easing but even that seemed like overkill. My solution was to rip out the parts I needed and I wanted to share how easy that process is.
