a new style of typing

i like this sign as it introduces a new way of writing. personally i’m not too bothered about capital letters. some people like them of course.
here we see a liberal lack of punctionation and an equally liberal use of capital letters. but note how the last letter in each word is still capitalised but slightly smaller.
that really cocks a snoot at those who believe sentences should start with a capital letter and end with a full stop.
like, how old fashioned is that ?
