Using a phototransistor and a big resistor could make the light sensing part work, though even with a high-pass filter, it would trigger on any fast enough ambient light change. Might be tunable, but I'd lean towards the tilt sensor.

That or a capacitive touch sensor. Putting some copper tape on the inside should be detectable with a mutual capacitance sensor. Pic related.
