Just wanted to point to some other cases where competition between attractive and repulsive interactions over different lengthscales gives rise to perhaps qualitatively similar patterns.

I'm not too convinced that the "stripes" are really stripes in that sense - the observed clustering is probably a nonequilibrium effect. The same clustering happens in strongly attracting colloids.
