I'm curious what the rationale is for drawing from a queue instead of directly in the move event.

Shameless plug: I threw together an open-source version for browsers (or mice, more specifically) this morning - http://news.ycombinator.com/item?id=1873371

Moving canvas operations out of event handlers is the key to smooth drawing on the iPad. The queue processor's inner loop is restricted to 10ms at a time every 30ms. This ensures a full two-thirds of the time is spent receiving touch events.

I was so excited, but ironically it does not work on iPhone (I'm still on iOS3).

What's ironic about an iPad app not working on an iPhone? They're related, they're not the same.

It is a version for browsers (or mice, more specifically). So instead of being mouse and touch event, it is mouse only.

It's not a version for browsers in general. It's an iPad web app.

Maybe a demo would help to the testing :) for those of us not having git (yet)

Good job, cool but styleless :)

Can this things be done with html5 svg?

Like I said, I just threw it together this morning - patches accepted :)

Solutions to your problem:

1. You should get git. This is the best one.

2. They support Subversion. svn checkout http://svn.github.com/mrduncan/marker

3. They have a Mercurial plugin that makes hg able to interact with git repos. http://hg-git.github.com/

There is a "Download" button on the upper right corner on github site. It will download a zip/tar.gz file with the snapshot.
