I had assumed you were using "interesting" in an ironic way, and were posting pictures of things bolted to something like tractor or truck wheels.  The items you posted look cool, but I'm not part of that big-boy league.

I can't say I've ever used something like that but thinking from logistics alone I can't see it scaling down too well.  At 1250 pounds it's hardly portable, at least without a forklift and a properly-sized truck.  I'm sure on big shows that's not much of a concern since the equipment would already be available, but I'd hate to need a forklift just to put up a simple 12" box totem or goal post!  I'd also be curious if they're more trouble than they're worth when trying to align the corners of a grid.  There must be a market for them though!

Makes sense for a big city rental house to have some. Not something to carry on tour, but I could sure see where they are going to be showing up on riders for name brand acts.

Interesting....  could see the use on an arena tour... but at that weight, your truck is at capacity with 48 of them (or maybe less)...  more I could seee a venue that commonly needs ballast, like a very large convention center, arena, or stadium, having some on hand because they also have the forklifts to move them, and never have to put them on a truck....

These look pretty well thought out.

Mountain Productions uses a similar base for their roof towers, although theirs are close to 7000 lbs.  They also have a plate on top that allows for fine adjustment of placement.   
1500 lbs or 7000 lbs, I still want an engineer to look at the application and make sure it is set-up safely and that there is a weather action plan in place for outdoor events.

Too heavy individually and too light when stacked and not enough footprint for most applications if you ask me. Plus, when you stack them you are shifting the center of gravity up.

For a roof system you need way more ballast than a stack of them will provide and for things like video walls you need a larger footprint plus more weight. I don't really see much uses for them except for the company to say "look, we made these". I'll stick with my bases and sandbags and ground stakes.

I'm used to seeing these personally.

For large stages I am used to seeing water ballast tanks with roof drains plumbed into them to keep them full in the event of rain.  Much lighter weight to transport as long as you have access to water onsite and the capacity to fill them in time.

I see similar things when lights are set up in parks for festivals.  The public can get up and touch/push against the truss, so it has to be super solid.
