Concrete5 add-on: Random Block
This add-on allows to display some random items (the number of blocks shown at a time is configurable) from one of scrapbooks that you can manage in concrete5 dashboard.
It is pretty useful when you have much information, but less hot space available to catch people eyes. For example, you can use it to display tip of the day, suggest something to try out, or just display images.
There is randomizer addon in concrete5 marketplace, this addon is not the same. We wrote it from scratch for one of our customers. It doesn't include sliding effects, etc. It just gives a random content from scrapbook.
