The flex workspace I rent in Amsterdam is called Concertgemaal. Each month the space is repurposed as a classical concert hall. To promote these concerts a flyer is designed by Bart van den Tooren (BVDT). Since I liked the design so much I flexed some css muscles and recreated it online. You can view it on the concertgemaal subdomain.
Sometimes the small tips are the nicest. If you own a smartphone or tablet it can be annoying to enter an email address in a regular textfield. If you fill out a form and select the email field you expect a virtual keyboard layout suited for filling in email addresses, not your default keyboard layout. The simple trick to get this field to behave is to use the correct HTML5 tag.
