The Lost Museum of Sciences

The Lost Museum of Sciences is a virtual museum which simulates
the experience of getting lost in a science museum. Unlike most
web sites, this deliberately confusing experience is designed to
promote unexpected learning and accidental discovery. The museum
features many hotlinks to a variety of museums throughout the
world. Furthermore, you are invited to play Find The Exhibit; a
global treasure hunt which challenges your power of deduction.
Everyone is welcome to roam the museum at their leisure.
