Dimension, perception and exploration of the Wonderland. In this paper we present a synthetic reflection about the meaning of Wonderland, as idea, imagine, illusion. In section 2 we show that a lot of Wonderland is born from phaenomena that appear to be out of scale, or at least out of logic. Section 3 underlines that a full sense of wonder is achieved when mutidimensionality is added to changes in scale and in quantity. Section 4 is dedicated to the possible ways of exploring a complex universe, as it is that of Wonderland; both environmental psychology and information theory are used. The conclusions say that to-day the Wonderland can easily be simulated by technological instruments, but all the same some kinestethic perception is required, just as it has been in the whole history of the wonderlands.
