Have you ever SSH'ed into a robot to debug whether sensors are outputting what they should? Do you find it cumbersome to launch rviz, port forwards, or fumble for HDMI cables every time you want to just see what the robot's camera or LIDAR is seeing? Do you have piles of unlabeled rosbags that you just want to open up and see what's on the images in them?
ROSshow is an open-source tool that use Braille characters to visualize ROS topics in the terminal. Besides time-series plots of most standard message types, you also get graphic visualizations of LaserScan, Image, CompressedImage, NavSatFix, PointCloud2, and more.
