"The Processing language was originally created at MIT as part
of the Media lab and Aesthetics and Computation group. They
needed a way to bridge the gap between software developers,
artists, data visualizers, etc., and to do so in a way that
allowed new programmers (or non-programmers) to do complex
visual work easily. Processing was built using Java, and can be
thought of as a simplified Java, with a simplified Java API for
drawing and graphics." (source) And so it is - with some little
tricks. First, Processing should get initialized in the html
page like this A Processing instance will be created, it can get
accessed via Amber in this way: processing :=
<Processing.instances>. After fetching this instance, it can be
used like any other Smalltalk Object: processing background:
224. processing line: centerX y: centerY dX: myDX dY: myDY. I
converted the clock-example to Amber, you can find it in the
Example-section of my Amber Git repo. And maybe soon in the
"official" Amber-Examples.
