An industry standard GUI? Tell that to anyone who tries to migrate from After effects to Flint or Flame. TOTALLY different GUIs. I use a Flint at work (as well as 3D MAX, After Effects, vizrt, Anime Studio, etc.) and find it quite similar to blender in a lot of ways, and not just the nodes. Maybe that's why I picked up blender so quickly. Is anyone going to tell me Flint isn't a professional tool? If you want to talk about a crappy GUI go no further than vizrt - far wierder and much worse than blender and it's used in professional TV production all around the world. The only barrier I'm finding to getting blender in at work is that the old "it's free - it can't be that good" paradigm. I'm using blender anyway, and people are gradually seeing the benefits.
