Construction bars from all over . . .

 In Case you missed it:
I make no claims of brilliance in creating any of these animated gifs.
 See my LINK PAGE wherein I give credit to those from whom I have borrowed these from.  
They no doubt possess the patience and perseverance to create them and therefore deserve all the credit.
 If you are the rightful copyright owner of any of these and do not wish me to include your creation here,
please email me and I will gladly remove them
