I thought having unavailable as a fence was self explanatory i.e. fences stop people going into certain areas..
This was something i did late at night and didn't put much thought into specific cursors so i couldn't think of a better object to use as the resize cursors other than sticks.
I was tired at the time and couldn't really be bothered to refine the images so they may be a bit blurry.
This is the second time i've played with the software so they are not going to be the best...
