This could be the fate of St Paul's Cathedral after a (tongue-in-cheek) application to the City of London for complete demolition of the 17th Century landmark. Perhaps for next week's Touch Up London, someone could put together what the cathedral's 21st century glass-and-steel replacement might look like? Before the wrecking balls move in, check out this wonderful lecture from Hooke and Wren biographer Lisa Jardine at the Royal Society, about the building and secrets......

With the rising cost of oil, and ergo jet fuel, it's about time we got round to establishing a permanent beach here in London. We propose Greenwich Peninsula, with its underused Tube station and impressive views. Buildings by daejn, beach and montage by M@. Do you have a vision for London that's more twisted than the Artful Dodger's DNA? Send your images to londonist - at - gmail dot com.......

With the Star Over London airship proving such a success, plans are afoot to give it a permanent mooring above St Pancras chambers. When not in service, the curvaceous dirigible will use the Barlow train shed for a hanger. Do you have a vision for London that's more warped than Captain Kirk's loom? Send your distorted realities to Londonist - at - gmail dot com. And browse our archive.......

Archiving is so important these days. Here's our vision of the ideal place to display former Fourth Plinth occupants. 'Old Stumpy' next to Blackfriars Bridge provides twelve storage pedestals for the growing collection of erstwhile Trafalgar Square plinthians. And how about employing Battersea Power Station's chimneys for the generally larger Turbine Hall sculptures? Got a vision for London that's even skewier than the Mayor's? Send your ideas and images to londonist - at -......

Here's an idea. Build temporary cofferdams in historic stretches of the Thames so that archaeologists can really get to work. It's amazing what you can find beneath a river that's served a city for 2000 years. Image by M@. Got an idea for a Touch Up London? Check out our archives, and send your own figments to londonist - at gmaildotcom.......

Another entry from Roll the Dice, showing a cunning method of crossing Tower Bridge without being stopped by tourists. Check out more Touch Ups in our archive and, if you feel inspired, send in your own photoshopped imagery of the capital to londonist - at - gmail.com.......

Regular reader Mehrdad collects unusual look-a-likies on his blog Aref-Adib. His latest discovery is that the Tube can bear a striking resemblance to the work of Dutch neo-plasticist (hey, we can use Wikipedia) Piet Mondrian.......

If we were Mayor, we'd order more bendybuses, not fewer as Boris would like. But why settle for just one concertina point? We'd fuse together all remaining double-deckers into a superomnibendysnake to convey tourists about town. All aboard! Please let us know what you'd do if you were Mayor via the medium of Photoshop. Send all entries to londonist - at - gmail - dot - com and we'll sort out some kind of......

For good or ill, a man can be prickly when pressed on the subject of his, ahem, endowment. Spare a thought, then, for Juan Pablo Di Pace, who has seen his manhood manhandled by the marketing department of the Royal Opera House. Cast in the crowd scenes for a 2001 production of Verdi's Rigoletto, Di Pace was surprised to discover some years later that his naked torso was used on posters advertising shows he......

A series celebrating the talent of our friends over in the Londonist Flickr pool who make our site look pretty with their fabulous photographs. Here, they introduce themselves and share their favourite London shots. Tower Bridge - Although I have done quite a lot of processing on this, I really wanted to get an un-cliched image of an icon that's been done to death. It was also a really weird light that day, which has......

Here we see a herd of Metropolitanus bestialacus encountering their rare, six-legged cousins the Metropolitanus aureus on the plains of the Serengeti. Indigenous to arid lands, these animals have evolved capacious water cavities along their backs to preserve the precious rainfall. Original background image from Kumasawa's Flickr photostream.......

Gold, frankincense, myrrh. What are these to a small child? If the magi were really such wise men, they'd have headed to Regent Street, where Hamleys and the Disney Store provide all the playthings a growing Saviour needs. Please send festively themed Touch Up London entries to londonist - at - gmail - dot com......
