How can he not include a video of it working? D:
i think its just people being out of touch with reality. perhaps engineering minds not thinking enough product. its too commonplace for me to even complain about. someone builds something primarily visual - a robot, a GUI application, etc. and links to their github/etc but they ensure that there are no visuals included.
In the results section it looks like there's supposed to be an image of it but the link "placeholder_rat_playing.png" returns a 404 :(
