Children attending grade school within the Setagaya Public School district created artwork for a digital aquarium at the museum that is projected onto its walls.
They had help from the first lady, who drew photos of fish for the installation. 
After she drew a purple fish for one vocal student and addressed it to the little girl, children crowded her, asking for autographs and drawings.
The first lady obliged and signed fish for many of the children, of which there were roughly 30 altogether, who'd gathered round and asked her for sea creature photos.
