I want to create multiple buffers one after the other. How do ensure that they show in a random order?

Ive got this piece of script. The intent is for it to display 2 squares and have a word in the centre. Im hoping to duplicate this many times and changing the word, font and the colours of the 2 cgrects. My question is, how do i randomise the order that theyre shown in once its been duplicated say for example 20 times.
cgloadlib
cgopen(1,0,0,0)
cgscale(30)
cgalign('r','c')
cgpencol(1,0,0)
cgrect(-6,-4,7,7)
cgalign('l','c')
cgpencol(0,0,1)
cgrect(6,-4,7,7)
cgpencol(1,0,0)
cgfont('calibri',4)
cgtext((colorword(:,1)),0,6);
cgflip
wait(5000)
would i have to loop the whole thing and set it up to show randomly? IF SO how do i do this?

Simplest would be to create N objects in (say) a cell array. Then generated a randomized indexing vector as |randperm
idxrand=randperm(N);
and then display objects in that order.
