Wow! The arrows just blew me away.

Hey I just noticed the ARROWS button at the top of the wind graph on the CSS weather page. If you're like me and never saw it before, go click on it. You will not be disappointed. (There’s a red message in the left column just above the Marshall cam saying “Try the Arrows button - - >” to point the way, in case your as dense as me, so unobservant that I just discovered it.) The arrows change color and direction in agreement with the wind direction, and they change speed, size and brightness corresponding to wind intensity. Unbelievable.
Great idea Ken. How did you create the arrow pattern? It has a nice random feel.
I watched the time lapse for Monday Dec. 24 and during abrupt changes you can actually see the arrows turn in mid flight. Its outrageous.
And now, just how dense am I? Tell me how long its been there.

That's what Custer said

I hadn't noticed them either. Nifty.


It IS fun on certain days

I've had that up since at least June of 2006, and haven't worked on it since then, for that matter. The arrows start out on a regular grid and each speed vector is slightly randomized, as are the angular rotation values when the direction changes. I played with the values and other parameters quite a bit to get an organic feel that seems to relate to how it seems when out on launch. Of course the single-point wind info gives a distorted picture. The colors are the same as used on the graph, and a key idea is that one can relate the directional-colors on the graph to the landscape at launch.

Good Flying,

Its a Work of Art

Great effect Ken, nicely realized.

Thanks for pointing out the

Thanks for pointing out the arrows Mike. We are all creatures of habit. I don't know how many times that I visit the same place on the web only realizing a long time later about a really cool link on the page that had probably been there a while. CSS sure is lucky to have Ken. Thanks very much to him we've come a long way since the day we first installed the windtalker. (1986) Back then we would have never even imagined the ability to even call the windtalker while driving. Now there are sometimes several conversations going on in the truck and nobody in the truck is talking to anyone else in the truck. They're all on cell phones. I suppose we'll some day very soon be all watching the Simba page on the internet monitor on the dash of our vehicles while driving up. Probably a couple or 3 monitors scattered around the vehicle too.
