Has someone been able to use the code written by fnf to make use of the Multi-Point capability of the Wiimote?

What Multi-Point Linux Applications are there available?

Unfortunately most X window managers don't support multiple pointers so user applications cannot do anything about it. Windows (and I believe Mac OS) also don't have this feature.

Chung Lee's demo of multi-pointer whiteboard made use of his own window and he was capable of processing the cursor events however he liked (even without multiple pens, he could still 'pretend' to have multiple cursors). That does not apply with normal desktop though.

That said, there is a modified version of Unix window manager which supports multiple cursors. I will look into that, but the user base is probably too small to be practical.

Here is another Multi-Point X Server.

I also found a blog with many links to Multi-Point info, it has a download section with some Applications for Multi-Point.

It seems like there are some Linux Apps, I haven't tested any yet.

These look much better than the one I posted :-) . I'll try those after finishing the config saving feature.

And for those following multiple input on Linux, MPX is now merged within X.org as standard.

From now on, every X manager will have multiple cursor/keyboard support.

What's special about this is that MPX works with legacy apps that do not use the MPX api. Programs that are multiple input aware will work flawlessly. In fact, once recompiling metacity, all gnome windows can be literally stretched at each corner at once.

The guys working on MPX are also working on blob-tracking code (what the wiimote hardware does). With software blobs, we can then define gestures within blobs. Blobs are within experimental MPX.

With MPX being standard now, Xwindows has something above the rest of the OS community: we can do what MS Surface can do without writing new apps, and we can do it right on our current machines, given appropriate touch-screen or tracking as seen on the Wiimote.
