A month or two ago I saw an image (IIRC on a Lisp blog) along the lines of

	= The Evolution of Lambda =
	McCarthy:	\x -> x²
	Bar:		\(x) -> x²
	Lisp:		(lambda (x) (* x x))
	W3C:

	<lambda><parameter-list><parameter>x</parameter></parameter-list>
	        <body><expression><operator>&times;</operator>
	                          <operand>x</operand>
	                          <operand>x</operand></expression></body>

Unfortunately I didn't keep a copy.  Does anybody know where I can find the
original?
