Try typing (1+2)*3 (parentheses are required). Open the
developer console to see node binding details. Next, try typing
and modifying the following example (the langauge has let bindings,
method calls, strings and numbers; shadow.png and
pope.png are the only two available images):
let s = image.load("shadow.png").greyScale()
let p = image.load("pope.png")
s.blur(5).combine(p,50)
