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><br></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><br></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> <div><br></div> <div><x-tab>        </x-tab>- Dan</div> </body> </html>
