Wallzilla killed the volume.
I'm really curious as to why there's a wall in many currencies.

Gox has only one market for all currencies. The bids/asks in any given currency are converted to show in all other currencies, with a exchange fee built in. The fee does not go to Gox, since they ironically are not licensed to exchange between various fiat currencies. Instead the fee goes to their bank, which does the actual fiat exchange.
The upshot is that if you place a bid in USD it shows up in Pounds, Euros, Baht, whatever else as well.

This is the most natural thing a multi-currency exchange should do. Of course if they take too high fees, others can do arbitrage for cheaper. Basically if the fee is 1%, an actual $$ wall should be 1% stronger than the auto-arbitrage--wall. A "buy 1000Ƀ@$120" would be a "buy 1000Ƀ@$119.8" in all other currencies. If you can exchange $$ for cheaper, you can squeeze your offer in between.

What explains that the walls are different size in different currency?
They are adjusted to relative volume.
