Can you randomize the triangles of an icosphere? Im really struggeling with getting this triangular structure to work.



Its like half an icosphere but with randomised vertices.



I already tried editing the vertices with random-proportional editing and then do a limited dissolve.
But this only works to a limit and gives something like this



If anyone knows a quicker solution than" do it by hand" id be so glad.

Please halp.

Edit:
Haunt_House`s answer worked perfectly
An easy way to get random triangles on any geometry is to start from a highly subdivided object and apply a Decimate modifier.

You will get nice regular triangles with the Collapse option. Use the Ratio to tweak the number of final faces.
