Hsinchu could use some more colour. It could use more artifacts on the walls too. It's rare to see any colour used in buildings in much of Taiwan making this wall, such as it is, a rarity. Even new structures suffer from this desire to remove any sense of an embrace of both the environment and cultural history. Taiwan's climate is sub-tropical which results a natural environment that is full of colour; lush greens and every bright colour imaginable are present. I don't know much about Chinese history but even a cursory look reveals some architecture full of ornate design and strong sense of colour. Singapore is full of colour, what happened to Taiwan?
Any discussion about the aesthetics of urban Taiwan tends to bring out extremely strong reactions (more so from the expat. community than the locals, most of whom are indifferent). No where is this more apparent than a popular Taiwan expat. community site called Forumosa. Forumosa is a great resource for the foreign community in Taiwan that succeeds in spite of itself; it suffers from a wandering focus, bad UI, and incessant tinkering to the live site. The discussion What An Amazingly Ugly Place is the latest example. People take things far too seriously.
These stickers (or artifacts) are everywhere, the random nature of which I find to be visually interesting.
