《Petalclouds》是新加坡樟宜机场第4号航站楼的中心艺术品。这个六角形的动态装置是在航站楼4号的精心艺术计划内委托和制作的。它横跨中央画廊屋顶下的200米。

总共有16个铝元素组成了六个动态雕塑之一，其外观不断而流畅地变化，类似于云。一种算法编排定义了雕塑的运动。形式、运动、光线和音乐共同创造了一种通感体验，并产生了新的形态。

编排围绕三种基本形式展开：随时间演变出复杂变化的圆形图案；可以横贯整个装置的波浪，从而创造出强烈的空间体验；以及形态变化——单独的云逐渐变形为较小的部分，展示出自己的特点，然后再融合为更大的结构并再次分裂。艺术品的和谐编排营造了一种宁静的氛围，平衡了航站楼其他部分的高活动性。

《Petalclouds》几乎可以从每个位置都看到和听到。冰岛作曲家奥拉弗·阿尔纳尔兹（Ólafur Arnalds）创作的音乐通过在航站楼内各处的扬声器播放。此外，过境旅客可以使用应用程序在自己的手机上听音乐。

内置在铝元素中的光带照亮了雕塑。光的动画强调了单个元素的运动，以及雕塑或整个装置。在后一种情况下，光可能会依次从一个元素移动到另一个元素，也可能贯穿整个装置。

每个圆角三角形元素通过四根细钢索连接到两个电机，可进行垂直和水平运动。为了设计复杂的编排，使用了专门开发的软件框架来模拟控制192个电机和灯光。

《Petalclouds》由新加坡樟宜机场集团委托。除了奥拉弗·阿尔纳尔兹（Ólafur Arnalds）之外，MKT AG Olching和竹中公司与我们合作开发和制作了这件艺术品。《Petalclouds》是我们在樟宜机场的第二个大型动态装置。自2012年以来，Ki­netic Rain为航站楼1号的出发大厅的繁忙过境空间增添了一种沉思元素。

Petal­clouds is the cen­tral art­work at Ter­mi­nal 4 at Changi Air­port in Sin­ga­pore. The hexa­m­er­ous ki­netic in­stal­la­tion was com­mis­sioned and pro­duced within Ter­mi­nal 4‘s elab­o­rate art pro­gram. It spans across 200 me­tres under the roof of the Cen­tral Gal­le­ria.

To­gether, 16 alu­minum el­e­ments form one of six ki­netic sculp­tures, whose ap­pear­ances con­stantly and flu­idly change – sim­i­lar to clouds. One al­go­rith­mic chore­og­ra­phy de­fines the sculp­tures‘ move­ments. Form, move­ment, light and music cre­ate a synaes­thetic ex­pe­ri­ence and gen­er­ate new for­ma­tions.

The chore­og­ra­phy de­vel­ops around three basic forms: cir­cu­lar shapes which evolve com­plex vari­a­tions over time; waves which can move across the whole in­stal­la­tion, for ex­am­ple, thus cre­at­ing a strong spa­tial ex­pe­ri­ence of the art­work; and morph – in­di­vid­ual clouds grad­u­ally morph into smaller frac­tions, re­veal their own char­ac­ter be­fore being con­sol­i­dated to the big­ger struc­ture and di­vided again. The art­work’s har­monic chore­og­ra­phy cre­ates a calm at­mos­phere lev­el­ling the high ac­tiv­ity in the other parts of the ter­mi­nal.

Petal­clouds is vis­i­ble and au­di­ble from al­most every po­si­tion. The music, which was com­posed by Ice­landic com­poser Ólafur Ar­nalds, plays through speak­ers at var­i­ous places in­side the ter­mi­nal. Ad­di­tion­ally, trav­ellers in tran­sit can lis­ten to the music on their own cell phones, with the use of an app.

Light bands that are built into the alu­minium el­e­ments il­lu­mi­nate the sculp­tures. The light an­i­ma­tion em­pha­sises the move­ment of in­di­vid­ual el­e­ments, as well as the sculp­tures or the in­stal­la­tion as a whole. In the lat­ter case, the light might travel from one el­e­ment to the next as well as through the en­tire in­stal­la­tion suc­ces­sively.

Each rounded, tri­an­gu­lar el­e­ment is at­tached to two mo­tors by four thin steel ca­bles, per­form­ing ver­ti­cal and hor­i­zon­tal move­ments. A spe­cially de­vel­oped soft­ware frame­work was used to sim­u­late the con­trol­ling of the 192 mo­tors and the light in order to de­sign the com­plex chore­og­ra­phy.

Petal­clouds was com­mis­sioned by Changi Air­port Group Sin­ga­pore. Apart from Ólafur Ar­nalds, MKT AG Olch­ing and the Tak­e­naka Cor­po­ra­tion col­lab­o­rated with us on the de­vel­op­ment and pro­duc­tion of the art­work. Petal­clouds is our sec­ond large-scale ki­netic in­stal­la­tion at Changi Air­port. Since 2012, Ki­netic Rain adds a con­tem­pla­tive el­e­ment to the lively tran­sit space of the De­par­ture Hall of Ter­mi­nal 1.
