Good fun in the old days! This one looks like it has some kind of electric control... can it be so? And if so, why? I like the tension in this image.... the marble run is the main subject but eldest (littlest? .... they grow so fast!) pulls my eye, which then moves back and forth between the two.
@yrhenwr No electric!!! This is the what we play with once electronic time has finished for the day!!! Tis littlest and yes they do so fast. Must stop feeding them.
