Frieda Lim and I helped install four new custom made window box planters at Brooklyn Botanic Garden last week. All of them are sub-irrigated and one of them has a special feature.
It has a viewing window so that kids of all ages can see exactly what is going on inside the planter. Growth of the root systems and status of the water & oxygen reservoirs is in clear view. This photo doesn't do it justice because the light was wrong. The last picture in this Flickr photo set will give you a better idea of the visibility through the window.
