The Vincent open source project is listed as official sponsor of the OpenGL ES 1.1 Coding Challenge:
"Khronos is pleased to announce the launch of the OpenGL ES 1.1 Coding Challenge. The contest will run in conjunction with the Khronos Developer University events beginning in Helsinki on Sept 17, 2004. The purpose of the contest is to create a library of sample code and applications for hardware accelerated OpenGL ES games, demos and screensavers that make people stop and stare with their mouths wide open, asking "That's running on a cell phone!?"
