I'm sorry but I really didn't like this- it's a shame because you had some great ideas for really original groups and it did all work- but you also have to give people a starting point, without having to make an enormous leap to guess what you were thinking- single letters are not enough information, there are thousands of possibilities- in a way it's therefore not a unique grid as you could combine them in so many different ways. Do, Do, Do keep trying though, there's obviously a powerful mind behind this, I'd be interested in what you do next, just please leave a "way in". Meant to be helpful I hope it's not too offensive to you :)

I liked this. Figured there would be elements in there somewhere and also letters that sound like words but I just couldn't find them! I was hoping there would be some sort of letter symmetry connection but there was not sadly. Decent, just like lorna said maybe leave a way in.

you're right! got a bit too carried away haha

must admit its cleverness but only line made any real sense to me (elements)
