klass = Kernel.const_get(myVariable)
foo = klass.new

See Module.const_get. Also, you can store a constant reference in a
variable too, so you can have the following too:

my_variable = my_class # note, I am not using a string here
foo = my_variable.new

P.S : underscored names are preferred over camel case in Ruby :).
