This site is build and maintained with Jekyll and hosted on GitHub Pages. Source code is on GitHub. I am using Twitter-Post-Fetcher to access my Twitter timeline and Unveil.js to delay the loading of images in galleries until they are needed. The typeface is Input by David Jonathan Ross. I´m purchasing it at Webtype, where you can test and play with any of their fonts for 30 days at no cost, until you decide what is right for you. The desktop variant of Input is free for private use and the web typeface variant is really inexpensive - lot´s of value for the money.

I build and share these tools:
