White lines in a black rectangle
A school board made of steps with formulas
Stylized image of the letter And in three-dimensional form
A dream among huge books
A schoolboy with a funny girl in his arms
Creative fusion of the two sides
IPhone as always boasts of its portability
Green men pointing in the direction
Japanese fan color on a light background
A ray of sunlight shines on an open book
People walk in the city park
A good picture on the desktop
