well basically the idea was to fill the sphere the best you can with random wheels - so yeah you get some empty areas - this can be improved a little but not entirely because connected wheels mean that the radius must be a multiple of a certain value (you can only have an integer number of teeth for each wheel so that Ri/Ni=Rk/Nk) - the problem is that for a random configuration you can't fit wheels everywhere you want to
the quality is lower for this one because I put some more frames and the images were a little more complex so I had to compress more to keep the size of the file within reasonable values
anyway if I find a way to improve this I'll sure as hell post it here
fcourse u can't fill where u want with random config. coz it simply won't turn in the same direction but u can configurate the radius of each one to fit so u can add some tiny wheels linking them all with some areas as some exceptions. still a good one anyway
if u can (i never tried it) the preview image would be smaller than the one in the download.. or if u can put them in an archive pack as high resolution would be soooo GREAT ! coz am those mekatrons.
