Keep it Simple & Consistent

Research into human computer interaction shows that humans prefer consistency in their computer interfaces. As a general rule it is best to stick with simplest and most consistent interface you can.

For example have all of your clickable items interact in the same way (eg. spin when user moves pointer over them), this way the users quickly learn to identify the interactive items. Although you could have 20 different actions occur when user moves over clickable items, a consistent approach will be most effective. Below are some tips for interactive items in your world:
