Rotating background (sky) based on the time of day
Hi. I have a very lovely backgrund for my homepage... and I had this idea: to make the background colors change based on the time of the day. Currently, my background has a light orange, yellow sky with clouds. (Sun rise colors). I made different versions: Noon, sunset, evening, etc..
I thought it would be really cool to time the background to change: for example around 5- 6 am, have the current BG, but during the evening, have the background change to a deep red/orange sunset background. Does anyone know how to program this?
Basically, it would be rotating images, since I have separate images for each time of the day. Does anyone know how to program a backgronud to change the image at the accored time? Please, please help! I appreciate all of your responses
