When the sun shines on the Internet. On 11 March, Mercedes-Benz is celebrating Convertible Day – and has developed an unusual banner motif for the occasion. What’s unusual about it is that, at first glance, it doesn’t actually look like a banner. Internet users initially frown when their cursor suddenly starts to cast a shadow on the site.
