Around 2000 or 2001, each of Alex Shinn, Vikram Subramanian, and Joel Smith either independently or loosely collaboratively, started writing Guile bindings for the SDL library. I asked Alex Shinn, who was starting to hack more with Gauche than with Guile, for project maintenance duties and he agreed. I have not contacted the others, but instead fished their names out of the various files found in the CVS repository tarball I received from Alex.
