Crop numerals

As distinct from crop circles, like you usually get.

In that spirit of not doing the usual - and because I'm quite likely not to notice when my 100th comes around - I thought I'd do a 'special' for my 77th. (Had I had a bit more foresight, it would have fallen yesterday... on the 7th...)

Pretty special, isn't it?
