Did you ever just created a server or a world to fool arround with friends? Or do you just want to have fun in some random area of you server? Then Fun Stones is the plugin to use.
The plugin will change the block the players are standing on into a random block(that being a block from a configurable list of blocks). This is done at a given interval, which is also configurable.
Here is a video of the plugin when it was really really basic, it is way more sophisticated at this moment!
How it works:
Just use the command /funstones to start the plugin, the plugin will keep replacing blocks underneath players until the command is issued again.
You can edit the config file to make a more personalised version of this plugin.
Warning: This plugin has no roleback function, and if used without care it can make of an once so nice area, an area filled with random blocks in your foorsteps!
