 1. `grid.rs`
     - Remove need for `deposit`/`deposit_all`
       - Possible solution: Make it so when data is called, it generates it in a function when needed
-2. Add check to make sure that `img_data_vec` isn't over a set size in ram, if so, render it and flush to disk
-3. Auto create gif instead of doing that after the fact manually with imagemagick
-4. GPU compute 
+2. Auto create gif instead of doing that after the fact manually with imagemagick
+3. GPU compute 
     - Tried [ArrayFire-rust](https://github.com/arrayfire/arrayfire-rust) didn't work well, looking for another library
     - Try using [emu](https://github.com/calebwin/emu) (seems to be a very good option)
     - Another option: [wgpu-rs](https://github.com/gfx-rs/wgpu-rs)
     - Look at [this](https://github.com/nicoptere/physarum) for inspiration
-5. Auto create a video from generated images
+      - Maybe re-write everything to run on the gpu instead of just offloading specific things onto the gpu?
+4. Auto create a video from generated images
     - Instead of using the command `ffmpeg -r 20 -i tmp/out_%d.png -vcodec libx265 -crf 25 -s 512x512 test.mp4` maybe use a rust library to do the same (more research needed)
-6. Live output
-   - Might want to do after #5 and #3
-7. Add config and cmd arguments when running the binary to adjust simulation settings7.
-8. sin and cos optimizations
+5. Live output
+   - Might want to do after #2, #3, and #4
+6. Add config and cmd arguments when running the binary to adjust simulation settings7.
+7. sin and cos optimizations
     - sin/cos table
       - precompute before simulation
     - Cache sin/cos values in hashmap to be recalled later
