but for the light to shift to the other pole you have to tilt the orange the other way.
The picture below seems as though the tilt hasn't changed, but look at the blue earth to you're left, the top portion with the red line striking thru
is tilted towards the Sun, on the right hand side you will see it tilted away from the Sun. What law of physics allows this? This wobbling science!

The Earth doesn't wobble. Your picture is a good illustration of what's happening: in the figure, the Earth's axis is tilted a little to the right at every point in its orbit. Objects in motion tend to remain in motion, so unless some force is imposed on the Earth to change things, its axis will always tilt a little to the right. The result is that the northern hemisphere gets more of the sun's rays for one half of the year, and the southern hemisphere gets more of the sun's rays for the other half.

one of the lunar cylces and the other of eclipses, we should be having and eclipse once a month.

Not quite. Your figure is a bit exaggerated. The Earth, Sun and Moon are much further apart, so the shadow cast by the Earth is much narrower than the figure makes it appear. Also, the effect is in three dimensions; if the Moon passes over or under the Earth's shadow when it travels through that part of its orbit, you don't get an eclispe. This is what happens most of the time.
The orbits of the Earth around the Sun and the Moon around the Earth aren't perfectly aligned; there's a bit of an angle between the plane that the Earth orbits in and the plane that the Moon orbits in. The only places a lunar or solar eclipse can occur is where these two planes come together, and an eclipse only happens when the Earth, Moon and Sun are all aligned properly at that exact time. All these things don't come together very often.
