元旦后，公园悄悄焕新了！
彩色琴键什么时候挂在墙上了？红黄蓝绿的长条板像简化版木琴，配色特别春天，敲一下能听见轻响，一开始我还摸不准这是啥，试着挨个敲了敲，居然能弹出 “1234567” 的调子，蛮好听的，还挺解压。
顺着小路走，湖边一排科学家科普立牌，绿白配色的展板上印着近现代天津科学家的介绍，拍到一只流浪猫蹲在旁边好奇的张望，阳光晒着湖水泛光，突然觉得知识和公园这样的搭配好新奇。
临湖设置了光影双色轮，透明彩片拼成的轮子转起来，地面会投出彩色光斑，两个轮同时或分别转动，光线透过重叠的彩色透明扇叶，会呈现出新的颜色，所谓“光的三原色混合”原理，坦白说我也不是很懂，但不妨碍我在旁边玩了很久
有童趣、有科普、还有美学，逛一圈像拆盲盒，把晒太阳的平淡都变新鲜了～
After New Year’s, the park got a quiet glow-up!
When did that colorful xylophone show up on the wall? Those red, yellow, blue and green slats look like a mini xylophone—super springy colors. A tap makes a soft, crisp sound; at first I had no clue what it was, but tapping each slat played “1234567”. Sounds nice, so relaxing.
Down the path, by the lake: a row of scientist info boards (green-and-white, about Tianjin’s modern scientists). I snapped a photo of a stray cat crouching there, staring curiously. Sun glints on the water—mixing knowledge with park vibes? Weirdly cool.
By the lake, a two-wheel light setup (transparent colored panels). Spin the wheels, and colorful spots splash the ground. Spin ’em together or separate, and light through overlapping panels makes new colors—it’s “primary color mixing” or something. No clue on the science, but I messed with it for ages.
Fun, geeky, and pretty—wandering felt like unboxing a surprise. Turned a lazy sunbathing walk into something fresh.
