For this project I tried to use turtle to create some abstract graphic that could interact with mouse motion. I use the turtle to make frames and another turtle to follow the mouse movement. whenever the mouse is pressed, a new turtle is drawn.

I wanted to replicate the effect of fireflies using the turtles. I made them move randomly and change direction randomly in order to do this over a dark relevant background.

For this project I decided I wanted to play around with how turtles worked and what they could look like, so I didn’t start out with anything specific in mind. I ended up with someone that looks almost like electricity – it reminded me of a plasma globe!

The screenshots of it don’t look very cool, you really have to view it in motion.

This does not look cool.

For this project I chose to work with the golden ratio turtle graphic that we did for the last assignment. I thought it would be cool to map this to the mouse Y positions to create different spirals. I then made three different turtles so that as you move across the mouse X positions you can play with varied sizes of turtle spirals. screen-shot-2016-11-12-at-8-47-25-pmscreen-shot-2016-11-12-at-8-47-59-pm

I spent a long time tinkering with the turtle trying to figure out exactly how to turn it towards the mouse, and it was such a relief to discover it was actually pretty simple! From there it was just tweaking certain numbers and values, and trying to get an interesting result.

This week for my project, I decided to make several repeating turtles with a changing background. It kind of reminds me of the pattern we had to create for a project in a past week. It was fun revisiting the use of turtles, and I enjoyed making turtles that looked totally different from the meanders we created for the assignment last week. I think the changing background adds a cool visual effect, and it was something I came up with during the course of making this project. I did not really start this project with an exact plan, like I usually do, but I enjoyed it nonetheless and feel much more comfortable using turtles now.

I really enjoyed this project.  I liked being able to add in the color changing functions because it added variety and made the turtle design a bit more engaging. sketch
