Srauch – Project 11 – Scrolling Landscape

My code shows a scrolling New Mexico landscape, with sagebrush in the foreground, sage-covered land stretching to the mountains in the middleground, and a mountain range in the background.

Project 11

Mon, 21 Nov 2022 04:02:06 +0000

The most challenging part of this project is figuring out how to construct the different objects. Objects have to appear and disappear on the screen at a constant rate. For my animation, I drew a bunch of bunnies racing and there’s grass, trees, and the sun in the background.

Srishty’s Project 11

Mon, 21 Nov 2022 02:27:50 +0000

The Sushi Bar Train

For my project I decided to create a restaurant on a train that serves japanese food via a conveyer belt. The dishes include: sashimi, tuna sushi, matcha, miso soup, ramen, and salmon. In the window of the train booth, you can watch as you travel through a bright city at night.

Project 11 – Generative Landscape

Mon, 21 Nov 2022 02:20:57 +0000

I combined handdrawn assets from a previous project with walking sprite from Assignment 9 to create a scene of a person walking outside. The sketchy ‘handdrawn’ aesthetic of the assets combined with the layers scrolling at different speeds to create a sense of parallax. Occasionally, another character will pass by between the layer behind the main character.

looking outwards 11

https://www.vice.com/en/article/4x4p43/6-art-projects-prying-the-lid-off-online-privacy

I chose the article showcasing 6 Art Projects Prying The Lid Off Online Privacy. I think vice did a good job of curating art pieces to showcase, and they referenced a good south park episode as well which I appreciated. The first piece was a browser extension that sets off an alarm everytime information gets sent to google called the google alarm. I think that’s pretty clever and is an interesting check in for when the system is keeping an eye on you, which is always. The other project that stood out to me was called My Little Privacy by Niklas Roy. He created a motorized curtain that covered a small portion of his street window display, and tracked people as they walked by. I thought it was an interesting metaphor, the idea of false privacy in the modern era. I mostly like the personality it has, it looks like it would be a lot of fun to pass by and it somewhat takes on a life of its own.

Project 11- Landscape

Sun, 20 Nov 2022 16:22:50 +0000

Graham Murtha

Section A

For this project I wanted to make a boat move through a fiery landscape, like the final world in Mario or Mustafar from Star Wars. I made moving embers, meteors, and randomly generated spires in the background to illustrate this volcanic landscape.
