Here are some images of a workshop for year 7 to 12 students at Thomas Tallis.  The workshop was delivered by Simon Thomas and was an absolute pleasure!  He showed us some of his current projects and we then built some models using straws, Polydron and Zometool. 

The yellow ones are made using straws and nodes usually used for making models of molecules.  You can buy them from Cochranes of Oxford here and you can get a maths kit made by Simon here.  They are particularly interesting because they bend, meaning you can create models with them that are impossible with other rigid model making materials.
