I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... Such emotions make a man forget food, sleep, friends, love... everything. (Nikola Tesla, 1856–1943)

these wise words by Nikola Tesla were artistically quoted by Matthew Inman
