Katsudö is a small and simple animation library for LÖVE

Here's an example:

local k = require "katsudo"

function love.load()
	gr = love.graphics
	gr.setBackgroundColor(213, 65, 0)

	tc  = k.new("tc.png", 30, 55, 18, 0.08)
	tc2 = k.new("tc.png", 30, 55, 18, 0.08, "rough")
	tc3 = k.new("tc.png", 30, 55, 18, 0.08).rewind()
	tc4 = k.new("tc.png", 30, 55, 18, 0.08).once()
end

function love.update(dt)
	k.update(dt)
end

function love.draw()
	tc.draw (50,  50, 0, 5, 5)
	tc2.draw(200, 50, 0, 5, 5)
	tc3.draw(350, 50, 0, 5, 5)
	tc4.draw(500, 50, 0, 5, 5)
end

And the result is something like this:
