Sorry! I went to sleep shortly after.
Is there a commercialized/casual aspect of eid that the award can be based on? For all the holidays we have already, we used symbols and traditions that are extremely far removed from the origins of the holiday. Did the original Saint Patrick have to do anything with beer? I'm not shooting down the idea. I'm just worried that if we choose a symbol too close to a respectable holiday and do it wrong, we may get backlash from people who do observe the holiday. I'm just thinking that it's safer to go on a more playful interpretation than an accurate and serious one.
I suspect it'd be even more frowned upon to work at a commercialized/casual aspect, but I understand what you're getting at.
I think a block of nice geometric pattern would be well-suited. Or maybe an Arabic lantern? Those are fairly standard symbols used.
