Great that you are going to do LSP meetups in Holland!
I’ve run 6 LSP Meetups in London – You can see photos and get a sense of what happened here
My learning so far.
Small is good. I’ve tried two sizes, up to 20 people and about 7. The bigger meetup had 2 facilitators and we had to juggle getting both groups to finish at the same time. It required a bigger venue and thus moving all the gear, setting up and then taking all the gear home again.
I run the smaller meetups in my flat. This makes the logistics MUCH easier, and has allowed me to do more work with smaller groups. To begin with I just did individual model building, then I realised I could do more. The last 2 meetups I’ve done shared model building, landscaping and connections. You can see the flow in photos of that here http://www.meeting-facilitation.co.uk/blog/files/what-happens-at-a-lego-serious-play-meetup.html
Martins thee objectives are about the same as mine. Though I’ve also set up ‘master meetups’ (the first this week) for certified facilitators to learn from each other. The model for this kind of LSP meetup is very similar to the IAF meetups I attend http://www.meetup.com/IAF-facilitators-and-friends/
I’d love to share any of the assets I’ve created…
I suppose my vision is for a global network of LSP meetups… and together we legitimise and expand the opportunities for LSP.
LSP is a brilliant tool, but not yet a mainstream facilitation tool!
Best of luck
