Focus on Designer Design task

This lesson follows on from the revision of a designer lesson in my resources. The reasonong behind the lesson is to reiterate the work of the designer but to also focus on some sketching skills and design thinking. There are 3 tasks.
1 Practicing sketching - Straight lines, Curves, Ellipses, Perspective, Coverging lines
2. Practicing shading and contering
(if you are not great at product design then I suggest you use this video from you tube https://www.youtube.com/watch?v=r-UqGtsjKiU )
3. Design a clock using sketching skills in the style of Phillipe Stark

There are some visual images that you can use for inspiration as well.
Not my greatest resource but could come in handy
