Ingress agents having fun in Westminster for Ingress First Saturday in London. We spotted pelicans while doing a banner in St James's Park! #ingress

It's Thursday night and I'm dancing around the moon at the Museum of London Docklands, but I'm thinking about 25 years ago when on a Thursday night, I would have been dancing at the Dungeon.

I played London tourist and jumped aboard the HMS Belfast. A vat of fake peas, many dials, ladders to climb.

Tunnels underneath the Brighton Pavilion.

A Laura Ashley fabric covered fence, in the Cosima Von Bonin exhibition, Upstairs Downstairs at Raven Row.

Today's sightings included a flash of bright blue above the river - a kingfisher! And a flash of bright red - a solar powered postbox!

Listening to extinct bird song and staring up at the giant Fibredog, a folkloric thatched creature, in the rain, at the Frieze sculpture park.

Tonight, a walk in the dark, and I've listened to the River Ravensbourne trickling and the trees rustling, and stood with one foot either side of the Meridian line.

Wandering around Peckham in the rain with a cardboard box on my wrist, listening to gates, manhole covers, walls, drainpipes, plants, after going to a Peckham Digital - Festival of Creative Computing workshop and assembling a "Surface Reader".

Getting up early and walking through the woods and swimming in the lake at sunrise feels like an adventure.

Three eyes I recently found on the Thames foreshore: 1. An eye from a bearded man on a Bartmann jug (16th or 17th century stoneware) 2. A pink eye, probably from a toy. 3. A mysterious blue eye, which could be a stone. #mudlarking

A mysterious metal object I found on the Thames foreshore, with "N P Brown" and "Prime" written on one side and "51" on the other. A token of some kind? What do people think? #mudlarking

The Thames is trying to craft its own tools.

A domino I found on the Thames foreshore. Has anyone found the rest of the set and wants a game? #mudlarking

Uranium glass found on the Thames foreshore, glowing brightly.

A fragment of what was probably a late Victorian Hooper Struve ginger beer bottle, found on the Thames foreshore. #mudlarking

A fragment of a Victorian marmalade jar, found on the Thames foreshore. Made by Maling, who were based in Newcastle.

In this version of London, marmite on toast ice-cream is edible but other food is not.

The Thames doorbell. A doorbell I found on the Thames foreshore. When you press it, it plays sounds of the Thames, recorded from the foreshore.

A Thames invader! A mosaic made from pottery sherds I found on the Thames foreshore. #mudlarking

Devil's toenails (gryphaea), a genus of extinct oyster. I found these fossils in Marske, in the north east of the UK. They are approximately 200 million years old, so a bit older than the oyster shells I've found on the Thames foreshore.

An echinoid, a fossilised sea urchin, found on the Thames foreshore. It could be about 80 million years old. Wikipedia says they are lucky and have magical powers. #mudlarking

I found the legs of a pirate on the Thames foreshore.

Dragging my suitcase back to London filled with devil's toenails.

On holiday in Doggerland, walking through the forest.

I ate the 3D printed vegan salmon at Unity Diner. Salmon 2.0.

Deep level shelter in Epsom. A municipal air raid shelter for 1500 people.

Waiting for the train: 1 seat taken by 2 wasps and 3 ladybirds 1 seat taken by 1 ladybird 1 seat taken by 2 ladybirds

The animals of South East London: Tuesday there were ducklings and dragonflies as I swam in the lake. Wednesday, there were bats and foxes underneath the glowing moon. Thursday, a loveliness of ladybirds flying about. So many ladybirds.

I found a hand on the Thames foreshore today. #mudlarking

A butterfly landed on a feather. A little egret flew away. The crows cawed loudly. And me? I was asked if I'd lost something.

I found a piece of a small pot on the Thames foreshore, that says "Oat" on it. It would probably have contained Oatine face cream, which was manufactured from 1905 to the 1960s and advertised as "the food for the complexion." #mudlarking

First session at Voidspace on Ambient Lit and I have been on a walk, imagining I'm a dog and chased some pigeons.

"G was a gardener who works many hours, H was a hot-house to hold his choice flowers" A pottery sherd that was probably once part of a child's alphabet mug circa 1830. Found yesterday on the Thames foreshore. What it might have originally looked like: junoantiques.com/childs-pearl...

I paddled amongst the starfish and moon jellyfish.

I have been outside in the pouring rain and whispered my secrets to the sea.

Today I found some Staffordshire Slipware.

Today's best find while mudlarking briefly in Greenwich: an eel!

The river was low enough that the fox skipped across it.

A quick wander to the foreshore at lunchtime yesterday revealed a piece of flint, pirate glass and pottery sherds.

Enjoyed The Engine Room sound art exhibition at Morley Gallery. The video is of David Sappa's Bouquet of Bones/Foreshores Rising, made of materials found along the Thames.

Things I found this evening on the Thames Foreshore.

In an attempt to train my eyes for mudlarking, I stared at the pebbles on the street where I live in south east London. I started noticing pottery sherds.

A week ago I went mudlarking on the Thames foreshore for the first time with my new permit.

"Do you love London?" a colleague asked, as we walked around the City one lunchtime.

I'm now a licensed mudlark, but the tide is in.

A guided tour was taking place on my street. The Walter Segal self build house, an obvious attraction, but I wonder what other sights were pointed out.

Fumaroles steaming at Vesuvius.

Gloucester Road station, London.

At Blackfriars Station, school children slide down the handrails and I wish I could do that too.
