A version of one of these might work for your dilemma. Surely one of them can be tweaked to work for your window.

I have a weird shaped window that I am having difficulty solving. I need to be able to control the light, while still being able to see out. The room gets cold in winter (south facing), and hot in summer (gets sun early morning and late afternoon). I need to control the light so my fabric and paper don't fade, need the lovely even light for working, and have a lovely view from my desk. Venetians or vertical blinds would be perfect except for the angles. Any suggestions?

It's the window leaf itself that has bowed. Have attached couple of images that hopefully explain it better. It varies with each window but a lot of them have just warped all kinds of ways. The one below is probably a bit hard to see but has bowed in the middle.

Hey all, we have a mid 90's house with a couple of glass brick windows, one of which has started to seep with heavy rain causing the interior sill Gib to crumble. How should I tackle this as I can't see any obvious area where water may be getting in. Cheers
