Domino movement

hello good folks of kirupa forum - im quite new to all this actionscripting stuff but I what i want to achieve i dont think should be that difficult - i just dont quite no where to start! -

what i want to do is have a series of clips on the stage - say balls - when i mouse over a ball the others around it move away - the distance they move is dependent upon their initial position in relation to the moused over ball. - the further they are (initially). - and obviously when you mouse out everything slides back into place…

ive seen this kind of thing out there - if anybody has any idea about the basic concepts etc. or can point me in the way of a tutorial - or even some code!

attached is a gif showing what i want to achieve…

any help much appreciated… :h:
