The form prevails over the bottom. This one is the new slogan that governs the creative intelligence of the contemporary societies. The taste by the aesthetic thing and the spectacularity of the package has supplanted, to a great extent, the rational budgets of use and the last meaning of the architectonic constructions, the cooking new features or the outlandish tendencies of the fashion. The 21st century has been red-baptize like the century of the appearances, in him who already nothing is what it seems. Far from the rational and functional experiences of decades back that persecuted with insistence the optimization of resources and the effectiveness taken until the end, in the times that run the answer of how it has replaced the habitual questions of why or why. The excellent thing now is the originality and the visual impact of the creations so that they can almost demand the attention of the man of our days, customary to everything and obstinate to waste the time in too complicated lucubrations. The time has been transformed into a little good that the individual cannot squander looking for in depths of the content. The continent becomes, frequently, in main the referring one of the reality.

In the eagerness to find something different the aim has neglected that grants to the things its reason to him of being and by which they were created. Constructions like the Guggenheim museum, of Bilbao, or the Opera, of Sidney, both with an architectonic beauty outside all discussion, are able to distract the attention of the visitor of the works of art, theater or opersticas that are developed in their interior. The magnanimous presence of its structure transfers to background its practical function and after all its more beneficial supply for the society. Also in other spaces of the creativity as the gastronomy or the fashion is observed, the eclipse of the meaning by the significant one.
