I found free versions of Bryce 5.5:

MAC http://www.downloadsquad.com/2007/06/16/download-bryce-5-5-for-free/
PC  http://www.download.com/Bryce/3000-6677_4-10696717.html

and will get these on the header soon, but I need to know , can I just install this over my free 5.0? I have the 5.5 ser.# if necessary .. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
