Hi DesuDeus, give the attached Randomize plug-in a try.

To install it, unzip and copy it to the \commands sub-folder. That will then make a new command available named Randomize, and you can set up a keyboard shortcut to launch it press tab and type in the name Randomize and push enter.

It will let you do a combination of random movement, rotation, and scaling on the selected objects. When it's calculating you will see things come through in waves, with all movement done first, then the rotation then the scaling after that, so don't worry when you don't see any rotation or scaling on the very first pass through.

Here's an example:







Hope it helps! There may be some bugs, I've only very quickly put it together.
