SINGAPORE: After the blue and black (or white and gold) dress split the Internet last year, netizens are scratching their heads again at the latest optical illusion. This time, it's a set of toy train tracks.
BBC Academy trainer Marc Settle posted a clip of his son's toy train tracks on Twitter on Thursday (April 7). The post has since been liked more than 2,000 times and retweeted over 1,900 times.
