I saw a really interesting piece of typography on the Sigma cosmetics website which can be seen in my post Inspiration for Social Media Icons. I was really surprised how the designer had placed the letters overlapping each other. I used Photoshop to separate the letters which took quite a long time.
I really like Core Sans so I may use it for my site. myfonts.com says ‘Core Sans is a simple and modern sans-serif font. Core Sans’s Latin alphabet has good legibility and is designed simply. It also says ‘We recommend to use for books, web, screen displays and so on.’
