Some time ago I tried to write some C code using GTK+.
I was interested in seeing what it would take to create some panels that were similar to the ones designed by Beppe. The code is written to run with the version of DttSP that uses FIFO's and to work with the Softrock. If I get time I will try to update it to uses the latest CGRAN version of DttSP and to also work with Ozy/Penelope/Mercury.
I fired it up again and this is what it looks like.
