Good call. I applied the 4 patches and now I can run osmocom_fft with the -F option succesfully.

However, it seems to be quite laggy, with 'chunks' of 'water' 'falling' at about 1 second intervals and not flowing smoothly.

Looks nice though :)

Your GNURadio is too old.

At the very least you need those patches: http://gnuradio.org/redmine/issues/596
And preferrably those as well : http://gnuradio.org/redmine/issues/601

Note that they're only changin python files and text template files so
you can "monkey patch" manually your installation, no need to
recompile everything.
