@martinus I thought ‘I should make this’ followed immediately by ‘I live in Ireland, sundials are useless’

@Squozen I'm not a scientist, but what about a raindial? There could be some downsides, like the angle the rain falls on it and so, but at least it also works at night? 😜

@martinus @Squozen In Ireland you might use the oscillation frequency and amplitude of pub customers.
