Seems only appropriate that Construct has an example gear creator
If only I had used this to make the logo...oh well
How to customise:
Change the width/height of the two circles in the middle.
The 'Gear' object has a private variable called 'spokes' which specifies how many spokes to make.
The width/height and position of the spoke affects the size of the spokes.
To get different shapes spokes you'd have to edit the image
I know its not very user friendly, so I challenge someone to make a better version
Oh after you run the program, you can paste it into photoshop or whatever...it automatically copies to clipboard
