I started making these acrylic recreations of CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) images late last year, and just came out with a new batch. These images are used by websites to prevent spam bots from creating accounts or posting content. Every time I find an attractive one online, I save it on a folder and then paint my favorites. They’re for sale at my Etsy shop. Know a site with great CAPTCHAs? Post it up in the comments!

    Aren’t the letters a bit too crisp to be captcha? Usually I have to squint and/or pull my eyeballs out to place directly on the screen before I can read the letters.
