Grid Framework version 1.3.0 has been approved by the Asset Store team. The biggest features of this release is the addition of polar grids. Check out the updated included examples to see them right in action. Notice how in the lights-out example the coordinates wrap around, meaning that once you've exceeded the maximum angle it start from the beginning again without you having to worry about anything.
A quick heads-up, version 1.3.0 has finally been submitted to the Asset Store. Remember, the price will go up to 25$, so if you still want it for 20$ now is the time to buy.
Here is a quick update: I have reached feature freeze for polar grids, meaning I'm done with all the features. Now I need some last polish and I must prepare new images for the Asset Store, then it's all good to go. So, what took me so long? Well, designing and writing code is one thing, then you have to put it to use This often reveals weak points, some things might seems counter-intuitive, or some things are more complicated to use than others.
