Quite apart from the standard wx GUIs, I've been playing a bit with OpenGL.

This one is the first of two open GL displays I've been toying with:


It's a bit like a combined waterfall and standard fft display and performance is surprisingly good! There's no legend and the scale markers mean nothing at this point, but at least it looks cool ;) Kind of an fft land.

I've been working on one for a while, it works well (and is fast) but
its a little rough. I believe that Matt has a fairly recent version of it in CVS.
It may also now be a part of gr-wxgui --- I don't know.
If you'd like the latest copy send me an email.

Has anyone contemplated a "waterfall" type spectrum display?
This might best be done when contemplating general data
display speedups and UI improvements.

Not that I'm volunteering, you understand :-)
