For general interest - my Dynamic Geometry Sketches site at has been updated with the following:
1) Concurrency & Euler Line Locus
2) De Villiers points & Hyperbola of a triangle
3) Fermat-Torricelli point generalization
4) Some Parallelo-Hexagon Area Ratios
5) Unproved conjecture: Nested Fermat quadrilaterals

and the Student Explorations with:
1) Construct a parallel-hexagon with GEONexT
2) Finding the centroid of a triangle with different weights at the vertices_ a gravity simulation
3) Do online constructions with GEONexT
4) Reuleaux triangle generalization (video clip)
5) Square Trigonometry
