IT's worth taking a look at the final assignment description on the class site
You do have to build a light fixture, and that's the central part of the assignment, but theoretically it could be controlled by a sound pendant. But don't make the pendant so complex that you don't have time for building the lamp. That's more the assignment for a wearables class, as wearable electronics are mostly always more work, hardware-wise.
Also consider the challenge of filtering the right sound from all the other sounds around you. This is no small task, sound programming-wise. The oldest example I can think of is from the 1970's/80's, the Clapper: https://www.youtube.com/watch?v=Ny8-G8EoWOw&ab_channel=JosephEnterprises. It looked for two sudden changes in volume in a two-second period. It has been duplicated by dozens of Arduino users. However, any two sudden sounds can turn on or off your lights. Google "Clapper bloopers" for more on that.
This might be a better project for the Philips Hue control assignment that is coming up. And of course for the final, with all that work, you'd still have to make a lamp.
This is fine, in fact it's half of the final. But you also have to focus on both the aesthetic and the functionality. If you focus only on the aesthetic, you have only done half the assignment. The goal here isn't just to make something pretty. It's to make something pretty and useful. See the many books on the shelves in room 460A or mentioned in the class bibliography for examples that do both. Personally, I don't think 3D printing alone works for an aesthetically pleasing anything. It can be useful for making structures, but the patterns that it generates in order to make a print are starting to get cliched. Look for those parallel lines, and you can say "hello, that's 3D printed".
On the other hand, the lamps you showed look a lot like some of the classic Art Deco period lamps (I love stuff from that period), and if you like those, get up to the NY Historical Society and see the Tiffany lamp collection for inspiration. Those were produced not with printing but with more traditional crafting, most of which you could do yourselves with the right parts.
And your lamp needs to produce enough light to perform the task it serves, such as lighting a reading desk or chair, or lighting a dining table. That part is not hard, you've already made lamps that can be bright enough, but you now need to combine them with structure.
We have a two week assignment on that in which you will be making a stage lighting controller. However, stage lighting a full production is more work than we have time to do in this class. In fact, there's a whole track on it in the grad design for stage and film dept here at Tisch. For more on this, see https://vorlane.com/basics-of-stage-lighting-design-a-beginners-guide/ or some of the books on it, like this list. I also like Jean Rosenthal's "The Magic of Light" book. But that assignment is not the final.
