In this product design unite, we learned about how to make a lightbox. It is hard but it is interesting. I choose a mountain and trees to discover the light. I like to Putin things together so I like this unit. The most interesting part of this unit is to look at the laser cut machines how to cut. “I learned a lot of different skills during the process of making my lightbox, most of which had to do with Adobe Illustrator. ” After it cut out I try to put them together and make it nice. I paint the mountain, trees, and clouds. There are several things I’d change about my lightbox. the first thing about my lightbox is I changed not to put the cap at the front because that will cover my trees and clouds. Second, I changed the way that how the sky looks. Finally, I finish all my work.
