Yellow sphere it is a work of Iris Tjasa‘s collection.

Yellow sphere. This image, besides playing on the chromatic contrast between blues and yellow/greens, evokes contrasting sensations. If on one hand it resembles a comfortable nest in which an egg has been laid, on the other it seems like a volcano about to explode with its hot core emerging in all its destructive force. This is the ability of an artist, to leave the mind of the viewer free without chaining it to sometimes incomprehensible definitions.
