The works are extensions and epilogues of the topics that Lam has been thinking about and concerned about. It expresses the essence of vision and its state in the era of blurred boundaries by thinking and calculating the distance from the sea horizon and the colour blue of the ocean. Attempts to rearrange the fragments to present a floating and uncertain state by using words, the properties of glass and light, the idea of camera lucida, and the frequency error of the camera, to explore the comprehensive of vision, truth, meaning, and memory in pursuit of ambiguity and obscurity, also to re-examine oneself.

4.52 kilometres means the distance between me and the sea horizon calculated according to the Pythagorean Theorem, which is an absolute fixed number, and I will not be able to touch it.

作品為林氏一直所思考和關注題材的延申與小結。以思考和計算與海平線的距離和海洋的藍來表達視覺的本質及其自身在界限模糊時代的狀態。企圖以文字、物質與光的特性及相機的頻率誤差來重新編排碎片化事物呈現浮動且不確定的狀態，以追求多義性和模糊性來探索那難以掌握的視覺、意義與記憶，重新審視自己同時帶出情感疏離與脆弱的特質。

4.52公里意指根據勾股定理我與海平線的距離為絕對的定數，而我將無法接觸。
