A visual artist from Chandigarh made an optical illusion portrait of Guru Nanak Dev on the occasion of Gurpurab. The portrait is kept at Gurdwara Shri Guru Teg Bahadur Sahib. The artist, Varun Tandon said, "I made this using 551 'Ek Onkar' (opening words of Guru Granth Sahib). You'll see 'Ek Onkar' if you take a closer look & picture of Guru Nanak Dev ji if you see it from a distance. It's an optical illusion. I've used 'Ek Onkar' in 13 different colours. It was made in 7 days. Idea was to do something different on Gurpurab.”
