• calcium imaging w/behavior
  • ImageWidget for calcium movies, gridplot for the rest.
  • 3D in an image widget with contours etc, use Martin Haesmeyer's video! https://figshare.com/articles/dataset/Mesmerize_volumetric_zebrafish_dataset/14748915
• 3D skeleton & tracks onto animal
• 2D skeleton & tracks onto animal
  • show past n_points and future n_points in trajectory using divergent colormap on line with rolling buffer.
• PCA plot highlighting points along with scrolling video
• Galaxy with tens of millions of points
  • https://github.com/vispy/vispy/blob/main/examples/demo/gloo/galaxy/galaxy_simulation.py
• Gaia dataset of the milky way
  • HR scatter diagrams, color based on properties such as metalicity, temperature, luminosity
    • 3D scatter cloud of the milky way on the left, and on the right a temperature vs. luminosity scatter HR plot
      • lasso selection to select subsets of the HR plot and show those stars in the 3D scatter
  • General use for catalogue exploration
  • fog shader?
• Basic zmq examples
• All or most examples from pyqtgraph?
• All or most examples from vispy?
• basic computer vision and image processing examples from skimage
• pytorch image examples
• opencv examples, should be easy to video and interactive versions of all the video examples: https://docs.opencv.org/4.x/d6/d00/tutorial_py_root.html
• 🟢 interactive sklearn examples, start with simple stuff like making a covariance matrix of some image data (handwritten digits?), and use a linear selector to go through the covariance matrix to explore what each row is. In combination with moving selector examples in docs #647 it will look great in the docs.
