There's talk lately of presentations and zooming in LK. Came across
this about a year ago. Implemented in flash I think. Just some fodder of prior art for review:<br>

<div>Regarding zooming UI's, in addition to Negroponte's early work
that Alan mentioned, you might be interested in this paper:</div>

We present a generalized definition of scrolling that unifies a wide
range of existing interaction techniques, from conventional scrolling
through pan and zoom systems and fish-eye views. Furthermore it
suggests a useful class of new scrolling techniques in which objects
do not move across the display. These "stationary scrolling"
techniques do not exhibit either of two problems that plague spatial
scrolling system: discontinuity in salience and the undermining of the
user's spatial memory.</font></div>

<div>We should notice that Antero was a co-author with Randy. In
fact one of the first experiments Antero did in the Lively project was
to play around with zooming worlds instead of our Squeak Project-like
wormholes. I thought we even had some code from this in our
repository, but I don't see it. [I see that we lost Antero's Sun
address from the mail list, so I'll CC him]</div>

<div>I just tried inspecting the world and evaluating
this.scaleBy(1.1) but i see we currently don't use the world's
transform (tsk, tsk).</div>
