Not quite a games workshop... but last week I ran a Lego for Library Teaching workshop in Manchester.
We had a full day of exploring the use of Lego (and to a certain extent, other building materials) in libraries / learning support. It's the first time I've spent a full day running a workshop on this, only touching briefly on it in other workshops before, and I really enjoyed it - I think the attendees did too.
The video above is a summing up of the workshop by an attendee (Lawrie), there are more available to give a flavour of what we did, as well as some pictures I took on the day... one of which is below!
Alicja has already written a short blog post of the day too.
