You can always be creative and make your own - mine is scalable because it is done in 'custom desktop logo' and it is scaled to the height of the actual flagstick itself - I make a note on the scaling factor for each flag in my WGT notebook and adjust it for the approach and flag at hand.
Could you tell me how you created this "cross-square"?
I just took a ruler from google and hatcheted away at it then put another one at right angles e.t.c......
The thing is to put it in to custom desktop logo so you can adjust its size, it's always worked well enough for me, but that side wind is so variable I usually just make a guess these days unless its a long way out.
Just hit me up if you want the .png file
You can also stick a 360 degree protractor in to it - just download 2 custom desktop logo programs - and overlay the wind arrow.
As for rulers I use the one by 'John Kummallil' on-screen ruler it's called it is also scaleable and comes with a range of different increments like inches, pixels, percent, pica........ it's very good.
I will check that one Don mentioned though, it looks good.
Then there's 'magnifixer' and 'zoom+' - they are the best magnifiers I have ever come across - they have the ability that not only can you magnify any part of the screen but you can put the magnifier anywhere on the screen too, it doesn't have to be directly over the arrow itself - and this is a very important and useful aspect that most other magnifiers don't have, I wouldn't be able to do see-click with magnifixer if it didn't have this property, just magnify the wind arrow so you don't strain your eyes reading off the angle.
And get 'always-on-top' from here:
It's just ctrl + space and it will keep anything you want on top of the screen.
Best stop watches:
I am putting these here as much for my own convenience because they are quite difficult to find online and finding the best ones take absolutely hours OMG you wouldn't believe how much time I spent getting the best stop watches, magnifiers.... hours and hours of downloading, trialing.......
Nobody said these things were easy to operate 'at first' - zoom+ is a pig until you get used to it then its an absolute doddle, they are all easy to use but you must spend some time getting familiar, I can't download you all a silver spoon as well you know lolololos.

MB Ruler (some great tools on this but his asking price for the pro version is ridiculous):
Fancy protractor (its not free and my way of overlaying is just as adequate):
