Hey,

I just launched a new rails app that _might_ just save you some dealing  
with  
vector-based graphics. Well for now it only does simple gradients and  
corners, but I’ve still found it useful.

Basically, instead of generating the image in Photoshop/GIMP and then  
referencing that file in your CSS/HTML, you just put the parameters in  
the  
url and the images are generated for you. A quick find and replace can  
change your color scheme without needing to go back to Photoshop/GIMP.

If you are interested, check out [http://www.thoughtless.ca](http://www.thoughtless.ca) or skip right  
to  
the examples here [http://www.thoughtless.ca/pages/api](http://www.thoughtless.ca/pages/api)

You will need to send me an email if you want to sign up. I think it is  
safer to start with a small beta.

Note: pretty much everyone on this mailing list is smart enough to  
‘hack’  
the access\_key, so that you don’t have to sign up for the beta. I am  
just  
going to ask that you please not do it. I will be fixing that soon, but  
in  
the meantime it isn’t a serious security hole so I’m just going to ask  
everyone to be nice. If you want to try it just send me a note, and I’ll  
set  
you up.

I am really looking forward to hearing what you think.

Cheers,  
Paul Cortens
