I had a small glass cut sample that I was prototyping for a project. While I was casually looking at it, an image suddenly came to me, and I gave shape to it as an aeroplane object. There was no particular purpose, no plan to present it, no background to talk about, and it was just quietly displayed by the window as one of my design studies, but it had a somehow cute appearance, and the shine reflected by the light from the window and the overlapping shadows falling through the multiple glass pieces were beautiful, and I secretly felt I felt attached to it. 
In a life with limited mobility, such as travelling and meeting friends far from home, the motif of an aeroplane attracted me, perhaps because it had a meaning or feeling that was unique to that time.
