Yiler Huang's Generative Flower

By Yiler Huang
This is my generative flower. The code will generates a small flower and a cross flower in random positions. The color of the cross flower is random. The small flowerwill be red if it's on the bottom half of the picture; it will be blue if it's on the top half of the picture.
這是我的生成花朵。該代碼會在隨機位置生成一朵小花和一朵十字花。十字花的顏色是隨機的。小花如果在圖片的上半部分則為紅色；在圖片的下半部分則為藍色。
