few weeks ago I was chatting with some of you on the IRC channel about GCSpy. GCSpy is a Garbage Collection visualization tool written in Java (currently a little bit outdated). It consists of 2 parts: server (which has a C/C++ connector to the VM implementation) and client (java application). Because of this demarcation, it is not tight to any specific VM or language. I am working on its rewrite and currently gathering ideas what could be improved (architecture, code, abstractions, ...).

If you are interested in, I wrote a document about the proposed changes and I am looking for further ideas. It will be great if you can provide any kind of feedback (general as well as what will be nice to add according to Squeak VM, ...).
