Locator in Manipulate's graphic.

Can anyone see a way to change the Locator's appearance in 
Manipulate.

i.e., from the documentation:

Manipulate[
  Graphics[Line[{{0, 0}, p}], PlotRange -> 2], {{p, {1, 1}}, 
Locator}]

I've tried the "obvious generalization":

Manipulate[
Line[{{0, 0}, p}], PlotRange -> 2], {{p, {1, 1}},
(Locator[#,Appearance->Graphics[Circle[#,2]])&}]

without success. Any ideas?
