The calliope plays 21 songs has an on/off switch and a volume control.  It is heavy and is about 4 X 7".

The OES are chasing lights across the top.  Each carousel piece (there are 6 - picture taking a merry-go-round and dividing it into 6 pieces of pie) has a light over the dog which moves up and down like a regular animal on a merry-go-round. 

Each carousel piece can be hung on a tree or it can be stretched out on a mantelpiece.  Each piece is about 7" tall.  The display can stretch out to approximately 6'.
