A scrolling marquee sign:
"Hi there! Welcome to the Department of Motor Vehicles Age. Please take a number and we'll call you when we darn well feel like it! Have a nice day."
Flashing lights:
Set up your panel that will be the cover with flashing lights. You can make your "Lights" any shape you want, round, square, button dome, etc.
Next, make a texture that blends like either the horizontal or vertical Ramps, only make it the color you want of your light.
Then make this the animated texture of your "light button" Frame rate will determine how fast your light flashes.
Set up a mesh like the ones we see on the Er'cana train. Make the texture like above to get the same result.
Blur something (this works, I tried it experimenting with water ripples):
After setting an objects texture, when you set the X or Y ofs, make it only 0.1 and the frame rate 5. The result will be a very blurry texture......make your eyes water it will!
Give yourself or your avie motion sickness:
Make a plane that's like a strip. Next, give it a texture like a road with a dotted line divider.
Then animate the texture. Give it something fast, like a 30 or 20 frame rate.
Link in and stand on it........if you look long enough, you just might get woozy, or feel like you're on a tread mill.
Actually, I had the world's shortest DMV visit a couple weeks ago: in and out in less than 30 mins...and I had not one, but TWO things to accomplish during that visit.
