Just CSS, no scripting language.

An auto-run slideshow in which images can be selected by a click/tap on any of the buttons along the bottom of the slideshow. After making your selection the slideshow will continue from the selected image.

On PCs, with the screen width greater than 1200px, moving the mouse over the slideshow will pause the auto-run which will continue when moving the mouse off the slideshow.

Those of you into lego will see that this is the model 42037 which I have converted to RC control using a 9 volt battery and micro toggle switch instead of the lego battery box which took up too much room.

The only major change to the model is to move the engine piston arrangement up one position to make room for the steering servo motor.
