This circuit causes a bicolor LED or two LEDs of different colors to alternately flash at a frequency that can be adjusted in P1 and which depends on C1. The circuit can be powered by voltages from 3 to 12 V and the values of R2 and R3 depend on the voltage. The circuit is from the book Fun Projects for the Experimenter by Newton C. Braga, published in the United States.
