+# you can make your own custom background for ted using a shader.
+# an example is provided here. you will have access to the following variables:
+#     t_pos - screen position of fragment (0,0) to (1,1)
+#     t_aspect - (window_width / window_height, 1)
+#     t_time - current time in seconds, modulo 3600
+#     t_save_time - time since last save, in seconds.
+# if you want your shader supported no matter what, only use stuff from GLSL version 110.
+#  on non-ancient computers, you should be able to use GLSL version 130.
+# bg-shader = "void main() {
+# 	vec2 p = t_pos * t_aspect;
