First, I thought a shape that specify transparent area, which is a cross in my assignment. After that I started to think how can i fill the space with which geometric shapes and stripes. I decided to use two color (black and lifht grey). Light grey areas indicate transparency and black areas show non-transparent surfaces. However, time was not enough for finising. I wanted to add more stripes for showing the cross transparent area. And also İ made a mistake in pasteing one stripe. I forgot to add black color.
