37signals' Chalk Dissected

I'm curious what the rationale is for drawing from a queue instead of directly in the move event.<p>Shameless plug: I threw together an open-source version for browsers (or mice, more specifically) this morning - <a href="http://news.ycombinator.com/item?id=1873371" rel="nofollow">http://news.ycombinator.com/item?id=1873371</a><p><a href="https://github.com/mrduncan/marker" rel="nofollow">https://github.com/mrduncan/marker</a>

Interesting (to me) UI insight: if a workspace is not scrollable or scalable, its dimensions are limited to the minimum common dimensions of landscape and portrait modes. Thus Chalk's work area is almost square.

Looking at the code I wander why didnt they allow this for the iPhone (it would be adding more media queries and nothing else). It would be pretty cool (mainly this is envy because me not having an ipad but an iphone).<p>Anyway, great app, they should enclose it on an iphone app with a webkit browser stripped down and offer it for free on the store (they have the other premium app with more features).<p>These guys are amazing

Excellent walk through. Great to see these new libs and touch-related additions in action.<p>This is also great example how web apps can replace native apps. I think we will see more and more of this stuff.

I always thought it was a shame that HTML only defined two elements for content: &#60;div&#62; and &#60;a&#62;.

Spot-on!
