I’ve just released version 0.1 of Liquid Canvas.
It’s a JavaScript library for drawing inside your web page. It works on top of HTML canvas, jQuery and excanvas.
On the Liquid Canvas page you’ll find a demo and an example of how it works.

$(window).load(function() {
$("#example").liquidCanvas(
"[shadow border gradient] => roundedRect{radius:50}");

With Rails 2.1 cache_erb_fragment has been replaced by write_fragment. This breaks a plugin I really enjoy to use: timed_fragment_cache by Richard Livsey.

Some usage examples – pretty self-explaining:
In your view:
<%- cache 'my_key', 1.hour.from_now do -%> ... <%- end -%>
With extensive queries – your view …:
<%- cache 'some_posts' -%>
