Hi Kiril, also if you want more info about scripting, one way is to look at existing scripts but also see here: http://moi3d.com/wiki/Scripting
for some additional information. See David's page for some documentation on what properties and methods are available on each MoI class, and also you can get the moi.idl file there which contains a all the stuff that is accessible to scripting in it.
Thanks Micheal, I'm quite content with the level of customization I can achieve now - I shall wait for something akin to JQuery for MoI :) before I invest much more time into scripting.
