[Elecraft] 3D spectrogram ???

[Kevin]

Has anyone used a 3D spectrogram program other than Ozone's?  I am 
digging for another but have been unable to locate a spectrogram program 
which utilizes a 3D display.  Ozone, with the 3D spectrogram, costs 
$999; a bit steep for an app I just want to test.  Their price seems 
quite fair considering the amount of programming effort they have put in 
to use both the CPU and the GPUs in a client's machine.  I would like to 
see the code but they are not in the open souce business.  They do offer 
a ten day fully functioning free trial, maybe that will have to suffice.
