As a big supporter of open source software I try to use and promote it whenever possible. Below is a list of software we use regularly on both our van build and this website.-ket
We use Blender for all the 3D design for our van. It is great for design, general modelling and animation.
We use digiKam to sort through and any retouch images in both our personal albums and for images we upload to this site.
We use Kdenlive for any video editing we may need to do, including videos we [plan to] upload on our Youtube account.
