Hello, I'm Niels

Web Application Architect

I turn ideas into code, and coffee into ideas.

Peppermint Wallpapers

100s of original nature photos are uploaded to Reddit every day. These make for amazing wallpapers, but unfortunately, most are lost into the void of the Web.

Say goodbye to your boring never-changing wallpaper: Now you have a collection of hundreds that's refreshed daily.
