Visitor of ours sent me this relaxing photo of a beautiful Hacienda. However, there is one (obviously hidden) thing in it. You’ll have no problem spotting it. How long did it take? A second or two seconds maybe? Even more?? If you don’t spot this one immediately, you can’t consider yourself an optical illusion expert :D I don’t know if this thing was made for fun, or the poster was actually used as an advertisement for this product (check the link only after you’ve spot the hidden object). The style author used, greatly reminds me of the Digital Swimming Pool illusion.
