On Area 51 I finally hit a captcha and was instantly depressed. It's the same as the Stack Overflow captcha :(

Can we please get something more specific and awesome for Area 51, hopefully falling in line with the rest of the theme.

  • Dumb question: What's a capcha? Is it the human-checker? – Jaydles Jun 5 '10 at 2:00

    @jay Yes. It is. – squircle Jun 5 '10 at 2:39

    Finally? I get those things about every five minutes. – delete Jun 8 '10 at 10:35
  • Maybe someone can find a public domain / cc image of the business end of a giant squid. By business end, I mean the razor sharp beak opened wide and waiting to eat you :) – Tim Post Jun 15 '10 at 16:58
  • Wow I add a bounty and instantly get 2 answers in about 5 minutes. – Earlz Jun 15 '10 at 17:24

    @Earlz That would be the goal of bounties :) – Michael Mrozek Jun 15 '10 at 17:43
  • Would someone post what it is? – C. Ross Jun 18 '10 at 19:11
  • @C. Ross: CAPTCHA Fail! Look a little farther down the page. – Dennis Williamson Jun 18 '10 at 20:06

If it's alien (well sort of) robots you want:

(assuming that this was the image I linked to in the first place)

  • excellent, we went with this for the captcha! – Jeff Atwood Jun 17 '10 at 20:02

    @Jeff - that's made my day ;) – ChrisF Jun 17 '10 at 20:08
  • What image was this? Is it the one from The Invisible Boy that's currently used for the captcha? – Laurel May 5 at 22:11
  • @Laurel - I can only assume it was the image of Robbie the Robot that is currently being used. I can't remember for sure and of course the link is dead now. – ChrisF May 5 at 22:15

  • I'm pretty sure that's still in copyright. Displaying it as something for the CAPTCHA page (rather than discussing the movie) is out of the grasp of fair use. IANAL, but I have one sitting next to me. – Tim Post Jun 17 '10 at 20:51
  • @Tim isn't that the problem with all suggestions so far? Maybe Terry Colon (Who did the Area 51 artwork) could be asked to draw something based on the top answer. – Tobias Kienzler Jun 18 '10 at 6:17

    That would be ideal. – Tim Post Jun 18 '10 at 6:44

    Aww, now my comment is obsolete. – Randolpho Jun 17 '10 at 13:59

    @Randolpho: You can take solace in the fact that your comment inspired me to change the image caption. ;) – gnostradamus Jun 17 '10 at 16:17

    But Wall-e is an eventual, not parallel future .. I'm quite looking forward to my floating couch. – Tim Post Jun 17 '10 at 20:46
  • Additionally, using this on a captcha page doesn't exactly constitute fair use (we're not discussing the movie on that page, after all). – Tim Post Jun 17 '10 at 20:59

There's always good old Cthulhu:


Not sure about ownership issues, though.


To make a kinder, gentler lord of the abyss and underworld, someone can just write (freehand):


... on the image.

    He's more of a "human-devourer" than a "human-checker". He'd be more likely to leave bots alone than he would humans, so he's kinda the "anti-captcha". – gnostradamus Jun 15 '10 at 17:03
  • @gnovices-exchange - good point, see my edit – Tim Post Jun 15 '10 at 17:06
  • And who says Cthulhu is not perfectly preserved somewhere underground in Nevada? – Tim Post Jun 17 '10 at 20:58
  • As to ownership...H.P. Lovecraft is now resting for a good 70 years...if someone is still holding copyright on that, then we have a problem with our system. But, if you mean the picture...there's a signature in the lower left corner...but I'm unable to read it. :/ – Time Traveling Bobby Jun 18 '10 at 12:01
  • @Bobby - yes, I was thinking of the artist when mentioning ownership. – Tim Post Jun 18 '10 at 14:38
  • @Tim Post: I've spent an hour looking for it, but I could only find images about that size (actually, about the same size) or smaller...it's all over the place but noone seems to mention where it came from, sorry. :/ – Time Traveling Bobby Jun 18 '10 at 18:34

Alright, I think we should go with a Gaius Baltar administering the Cylon Detector Test theme.

Here he is administering the test, with benefits:

possibly NSFW link

But that.... might not be fully work safe. So.... here's a pic of him looking at his own brain scan; it's "test-ish" so maybe that'll work.

We could go with just a Cylon:

Or Old Skool:

There have been any number of human-checking techniques in science fiction. It's an important plot element when the aliens or robots look like humans. Recent (relative to copyright) examples include V and Terminator. I can't think of an example right now that might have an image that's in the public domain.


C3PO and R2D2

    Still, again, much in copyright. – Tim Post Jun 17 '10 at 20:57

I came across this movie-poster from Houdini's silent movie from 1918 called The Master Mystery which illustrates the human/robot relation quite well. Though I'm not 100% sure, I believe the robot could be an actual person in a suit..

So considering that possibility we should introduce a captcha to let robots proof that they aren't actually just disguised humans ;)

It should be an alien robot.
