I have looked for about 15 secs at the pic, then returned back to forum to read the rerst of comments, and I have just heared that "AAAAAAAHHHH!!!" ( I open the links in new tabs, btw.). First time I thought that my imagination makes me hear strange noises, but after I have reloaded the page ( again, after 15 secs I comed back to the posts to read the rest), I've understood: my ears are healty, it was not imagination, that sound was real.
