Back on 2013 Neil Cicierega released to the public a tool on his Tumblr. Since the download link is broken and I found the concept pretty cool, I decided to recreate it my way with AutoHotkey. This is the first ever program I wrote using this language, so if you think some changes can be done, let me know!
Download the .exe of your choice on the releases page, there's a version in English and another in Spanish. You can also get the source code and compile it yourself with AHK.
PS: This only works on Windows!
