I've created a chain of nodes. In each of those nodes, I want to put other rectangles with text inside. This is how I want each chained node to look like (please excuse my touchpad drawing):

I tried to get this result by nesting nodes, but the node content seems to be in text mode, so that didn't work.

chainmatrixnodes, but I've never tried. Thematrixwill be your cyan square and nodes inside your yellow and violet boxes. – Ignasi May 03 '13 at 11:16
