How to make objects spawn around you like this?

Background

In this DBZ game there are brick particles that spawn around the player and slowly float up and rotate as if there's no gravity around them.

-Example: {https://www.gyazo.com/07dd3dc17728c553863c922c252341a0

Question

1. What are some ways I could get the bricks to randomly spawn around me in this manner (in front and behind).

2. How would I make them float as shown?

3. Is there a way to get them to spawn in a circle around me?

1. This can be done by either using constraints or CFraming.

2. You can spawn them on the borders of a cylindrical space.

local fxz,fy=function(poff,t)--[[stuff here]]-- end function(poff,t)--[[stuff here]]-- end
local parts = {}
local st=tick()
game:GetService("RunService").RenderStepped:Connect(function()
      local cp = HumanoidRootPart.Position
      for i,v in next, parts do
             local x,z=fxz(v.Offset.X)
             v.Obj.Position=Vector3.new(x,fy(v.Offset.Y),z)+cp
      end
end)

You can spawn them by using math.random and give them a body velocity to make them move upwards. (Just imagining what you mean since the gyazo isn't working.)

For example, this will make them spawn in a range of 40 or -40 studs away.

part.Position = character.Torso.Position + Vector3.new(math.random(-40,40),math.random(-40,40),math.random(-40,40))

As for making the body velocity, just create a new body velocity and set it's velocity upwards.

local bv = Instance.new('BodyVelocity')
bv.Parent = part
bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
bv.Velocity = Vector3.new(0,5,0)
