Hi, Edi. I just wanted to let you know that I had some trouble compiling TBNL 0.3.11 in SBCL 0.8.19:

You can type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

Looks like SBCL is expecting an UTF-8 encoded stream. But this is a JPG file and should be read as a sequence of octets. I'm not familiar with SBCL's new Unicode facilities, I guess you have to provide the right external format when opening the stream. TBNL on the SBCL/Mac combo won't work, though, because TBNL needs threads. Cheers, Edi.
