Comment (by isis):

 I spent about half an hour last night reviewing and testing the spideroak
 python/gimp captcha generation script. It works. I tweaked it a bit (to
 make it harder, actually, since by default it's only 5 letters/numbers).

 Before I go any farther, there are the following open questions about
 doing local captcha generation:
   1. Can this run on a headless server?
   2. This is highly resource intensive, on my laptop it took ~8 minutes to
 generate 2,000 captchas. Can BridgeDB handle this? Should we run it
 elsewhere and sync them to BridgeDB?
   3. Is this something we want?

 For making this easier for mobile users, there is
 [https://ux.stackexchange.com/questions/51864/captcha-on-mobile-whats-the-
 alternatives/51867#51867 this SE answer] which includes
 [www.josscrowcroft.com/projects/motioncaptcha-jquery-plugin/ a mobile
 captcha HTML5 trace system], however it uses HTML5 canvases.
