And of course, you can get out a playfield, fiddle with its options
to allow it to be picked up, make it transparent, etc., then put it
back in supplies, and it will form a prototype of this kind of playfield.

put them in the playfield. (This could be a smoother smarter
operation than the current situation in Etoys.)
