Thank you David and Xavier for sending me these most recent optical illusions. As we see, Bose has created some pretty neat optical illusion ads. Bose is a world famous company that sells higher end Hi-Fi audio devices, and this is why they used few of the most famous musicians in their campaign. If you look more closely, you will see that all of the faces were created from audio components and Hi-Fi parts. I bet Bose had great dose of inspiration from Harley Davidson’s Motorbike Faces and ClubMed. The author behind this creative idea was Nirmalya Chakraborty. Can you recognize all of the celebrities in this collection? Which one is your favorite? I like Elvis the most :)
