FIGURES IMPOSSIBLES

Els alumnes de dibuix tècnic de 2n d'ESO han realitzat una instal·lació a les escales de l'escola reproduint figures impossibles. Un objecte impossible és una il·lusió òptica consistent en un dibuix en dues dimensions que sembla representar una figura tridimensional; és a dir, és la imatge d'un cos que no pot existir però que la ment veu com a factible a simple vista. Serveixen per estudiar les lleis de la percepció humana. Alguns objectes impossibles coneguts són el triangle de Penrose i el blivet.
