Desmo Animations

I digged up already > 70 ever produced desmo-systems.
Twentyfour minus ten solved in the mean time makes fourteen* systems that are still more or less a mystery to me.

Who can solve the hereunder mentioned mysteries? Pictures; drawings; articles; everything is welcome!
Please take a look at "Systems" also for further information.
Contact me by [In Dutch; English; German and French].
