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.

A cardboard box strapped to a wrist, with a contact mic extruding over the top.

It's the latest fashion

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.

A pottery sherd with an eye and a nose on it, from a Bellarmine jug. A blue eye that is maybe a stone. A pink eye. (Please note, you need a permit to search or mudlark on the Thames foreshore.)

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.

A worn metal rectangular thing with "N P Brown" and "Prime" written on it. There are some tiny words under Prime that could say Johnson but they are difficult to make out.

A rusty metal tag that says 51 on it.

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

A rusty piece of metal with a shell attached at the top.

A rusty piece of metal with a shell attached at the top. Shell ridges more visible.

The Thames is trying to craft its own tools.

I did. Such pretty demonstrations!

I was there earlier too! But probably left before you got there. Seems I missed many people there by going early.

An old domino. To search or mudlark on the Thames foreshore, you need a permit.

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

A glass shard glowing brightly under a UV light.

A collection of mudlarking finds, mostly pottery sherds, but also a yellow glass shard. (You need a permit to search or mudlark on the Thames foreshore.)

Uranium glass found on the Thames foreshore, glowing brightly.

The bottom of a ceramic jar, with the words "Maling" and "Newcastle" written on it. Found on the Thames foreshore. You need a permit to search or mudlark on the Thames foreshore.

The Thames must consume a lot of marmalade. Another piece of a Victorian marmalade jar I found on the foreshore. #mudlarking

A brown pottery sherd that says "Hooper" on it. A permit is needed to mudlark on the Thames foreshore.

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

I did not lick it to see if I could taste the marmalade.

A large pottery sherd with many cracks that says "Maling" on it. Found on the Thames foreshore, with a permit.

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

I just assumed they were Enl in disguise.

The Bourdon Street Chippy by Lucy Sparrow. The food is made of felt.

A slice of bread that looks mouldy but is made from gemstones and a mattress, at the Gagosian, by Kathleen Ryan.

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

Thank you! I suspect when it was functional, you could press it and Old Father Thames would jump out from the river to greet you.

I have just watched a video of it now, and yes, that would indeed work with a doorbell!

Ha, I don't think I remember what that sounds like.

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 mosaic in the shape of a space invader with black tiles on the outside and blue and white pottery sherds and white grout.

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

Gryphaea fossils. They mostly look like grey stones.

Larger gryphaea fossils, with more details on the shells.

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.

A fossil with five petal shapes coming out from the centre. Found on the Thames foreshore, with a permit.

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

Apparently from a 2008 Kinder Surprise toy: en.todocoleccion.net/rubber-pvc-f...

Plastic legs of a pirate that are pink and white and a bit worn. The pirate is also wearing a belt with a sword and shoes, but the top half of the pirate is missing.

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

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

The petrified remains of a tree stump on the beach in Redcar. The sea is in the background.

On holiday in Doggerland, walking through the forest.
