The London Design Festival is upon us again, now in its fifth year, and we've just picked up the festival guide, which weighs in at a cracking 258 pages. That's partly because it has some extended essays at the front, but also because the event just keeps getting bigger.

As with last year, we've put together a list of the events we're going to try to get along to this week. You can pick up a festival guide at most of the venues, or from the festival hub at the Royal Festival Hall on the South Bank, or just check out the festival website. Icon magazine has also produced its own guide to some festival highlights, with a particularly useful day-by-day guide to private views and parties.

LomoWorldWall
The Lomography gang have put together one of their Lomowalls in Trafalgar Square, featuring over 100,000 lomographs, which will be added to during the week, culminating in a big old event on the 22nd.

Size + Matter: The Materials Project
Zaha Hadid, and Amanda Levete (from Future Systems) have created a couple of one-off pieces outside the Royal Festival Hall. We saw them being installed on Saturday, and they were already looking pretty groovy.

Tom Dixon: Great Light Giveaway
Last year Tom Dixon gave away a stack of polystyrene chairs in Trafalgar Square, and his generous nature is still in evidence this year. He's created a low-enery light installation at Trafalgar Square, which kicks off today, and which will be lit for a few hours each day (from sunset, which is at 7.15 today according to BBC weather). He's giving a stack of his Blow lights away, though quite how you get them depends on who you listen to. His site says it's a first come, first served kinda thing, starting at 5pm on Wednesday, giving away 500 (or possibly 1,000) of the lights; but the LDF site says: "A certain number of tickets will be issued to visitors on each day of the installation, and on the final Saturday all 2,500 lights will be given away to their recipients". Guess the best bet is to pitch up when you can and ask the folk there.

UPDATE - We nipped along there today: the installation runs till Wednesday evening, lighting up from 7 till 10 on Tuesday, and 4.30pm till 10 on Wednesday. At 5pm on Wednesday they'll give away 1000 lights on a first come first served basis. They're already giving away free Glowb low-energy light bulbs.

Conversational Spanish 2
A show of Spanish design curated by Hector Serrano, 10 to 6 daily from Tuesday, at 67a Great Titchfield St
W1W 7PT.

Designers Block
The younger, more interesting alternative to 100% Design, back at the Nicholls & Clarke bulidings (3-10 Shoreditch High Street) for their Tenth Anniversary show. Expect lots of great product and furniture design. It's on from Thursday to Sunday, from 10 to 7 daily. Register online by Wednesday for free entry. Check their blog for more info too.

Designers Block: Illustrate
Not content with all that action on Shoreditch High St, Designersblock has also got an illustration show over at Highbury Studios (Hornsey St, N7 - near Holloway Road tube), running all week, from 10 to 7 daily, with work from over 80 leading illustrators.

Super Design Market
The folks from Scarlet Projects (they're the people behind the V&A Summer Fete) launched the Super Design market last year, and it's a great chance to pick up some tip-top bits of design for between £5 and £100. It's in the Ballroom at the Royal Festival Hall, Friday 6-9, Saturday 10-7, and Sunday 10-6. Go shop.

100% Design
It's a bit of a corporate behemoth, but Tom Dixon is the creative director this year, so it could be interesting, and it's got a fair few off-shoots too (100% Light, 100% Sustainable, 100% Materials, 100% Futures etc), which should be worth checking out. The public day is Sunday 23rd, from 11-6.

Tent London
Taking over where 100% East left off last year, this event fills the Truman Brewery on Brick Lane from Thursday to Sunday. We're particularly looking forward to checking out Alex Haw's solution to the Urbantine Project.
