Here is some more at Tweelijners. A set of descriptions (including some flight properties and history) and plans of the Belgian kites (Le Quartz, Horizon, L' Organic, Temppu Leija, B'zar and Le Vortex) can be found at:

No, no building for me as it looks like today - that would take the time I have/take for flying (and I never had a sewing machine anyway). However some dreaming now and then is an available option and is also free of charge.
There is a video of these kites, "Le grand Organic à la plage", that I like much. It is playful, artistic, shows nice coastal views, good flying and seems to be filmed with high quality gear and is well edited. Don't watch this on your mobile since the mood of it might not be conveyed! See and listen in front of a decent monitor and give it your attention during it's full 8:27 minutes!:
