[REBOL] - Old Hippy Needs Help With Clouds

From: jimbo:sc:starcat:ne:jp at: 4-Jun-2001 16:32


Hi guys,

I wanna render a really cool earth with animated atmospheric cloud layers!

Ok...  I know Lava (Errr.. REBOL) doesn't render worlds but it can help!

Here's how:


There's a wether site that posts fixed orbit sat. photos of the earth's cloud layer at 
30 minute intervals.  They're always posted to the same URL but DL in my browser ("Save 
Image As") as different file names:

    GOES04452001155k2wqmz.jpg
    GOES04152001155ernztH.jpg
    GOES03452001155EQIk05.jpg
    GOES02452001155jLxZMS.jpg
    ...
    etc.

I want REBOL to:

  1.. Grab the image off the site.
  2.. Save it to Disk under supplied filename or specified sequence name.
  3.. Wait exactly 30 minutes.
  4.. Repeat until aborted.


I did some beta testing befor the initial pubilc release of REBOL so I'm pretty sure 
this is doable but I haven't looked at it again since and feel a bit lost...  Sorry if 
this has already been discussed here.  Is there some example code I could look at that 
would do this from a URL like:


http://wwwghcc.msfc.nasa.gov/cgi-bin/get-goes?satellite=Global Composite&x=0&y=0&map=none&zoom=1&width=1000&height=500&quality=100


This has got to be what?  Maybe 5 to 10 lines of code...  The only problem is it's 5 
or 10 lines of code I don't know and I looking for a quick fix.

I would be very very greatful for any input you could provide.
