Honestly... first of all I don't understand the reason to override the standard windows cursor, for standard pointing at things. It just makes things confusing. Especially for someone who has used all his life a black cursor using Houdini with a white cursor is just weird. Now... about the pointer design in itself: I think we could have done better.
Given how AMAZING the Houdini icons are, this just feels like a big oversight.
Heileif I never noticed the cursor was different to be honest.
And yes, the Houdini icons looks great!
That's weird, because I think that not even the shape matches the standard windows pointer -don't know about other platforms. But if you were using a black cursor you would probably have noticed it.
