This new museum combines science and art.  It is very unique, and very "hands on".  Both adults and children will enjoy the interactive exhibits.  Everyone will enjoy making thier own stop animation movies or seeing themselves turned into a virtual character.  There also was an exhibit of photographs documenting the racial struggles in the 1960's which was very moving.  The Leonardo is right next to the Salt Lake Library.
