Hi All
I have published a simple mapping node that lets you put blobs on a map like this

It's a contrib node as it's really for use as-is , and doesn't quite fit the mould of other nodes yet... You will notice it has no inputs or outputs... just contributing a web page endpoint - that you then point a websocket at... (much easier than having to rebuild all the websocket code again :-)
If you are on Node-RD v0.13.4 you will see some simple examples of use in the Library (once installed).
