Anyway, you can find them at: http://dasim.gswce.net and http://ddsim.gswce.net. The presets are a bit random at the moment, I’ll need to rationalise these over the coming months before they get out-of-hand.
There’s a basic “getting started” video for dasim on Youtube here: https://www.youtube.com/watch?v=f0WXNklf_CU although it’s probably out-of-date already.
When I get something a bit more stable working, I’ll update the versions here. In the meantime, any comments very welcome.
