Clowning, despite its association with great funnymen such as Joseph Grimaldi and Charlie Chaplin, has always had a dark underside of melancholy or even menace. More latterly it has been thought of in terms of “low” arts such as circus and street theatre, and so it perhaps shouldn't come as a surprise that fear of clowns, coulrophobia, is in the Top 10 list of phobias, up there with spiders, enclosed spaces and vomiting.

At last a terrific show in this year’s mime festival - Du Goudron et des plumes (Tar and Feathers), in which you gasp at the brilliance with which the French acrobatic troupe, Compagnie MPTA/Mathurin Bolze, invent a wondrously unstable world on a swinging raft that's deliciously mad and imaginative. It’s as if echoes of a children’s game on swings had suddenly mushroomed into a sphere of its own sound and motion laws, and in the dark, bare Barbican Theatre is a perfect place to watch it. Hurry - you have just two nights left.

The puppets appearing in LIMF this year are by no means all child-friendly - after the mild kiddy-horror of Teatro Corsario and their hand-manipulated Bunraku creatures, the return of the much more disturbing imagination of Patrick Sims, founder and governing mad scientist of Buchinger’s Boot Marionettes, was my most-looked-for event.

It’s mime time in London. The new year is always ushered in by a motley of theatrical varieties, from puppets and acrobats to illusionists and mimes - it’s certainly an up-and-down ride in the London International Mime Festival. It began this week with an up in the shape of a spooky children’s puppet show based on Edgar Allan Poe and a down in the tale of an office invaded by wildlife.

The mistake was probably that I hadn’t tanked up beforehand. Clues were there. Soho Theatre is over a pub. 9.45pm start. Who’s going to turn up in those circumstances completely sober? Who would be mad enough to turn up in Soho at 9.45pm stone-cold sober? And a four-star Edinburgh Fringe show had not necessarily been assessed by altogether un-punchdrunk viewers, lurching as they do (and I have done) between five shows a night.

Compagnie Ieto are two modest Frenchmen with immodest circus skills - modesty in all the right proportions. Jonathan Guichard and Fnico Feldmann teamed up in 2006 and were finalists in the 2008 Jeunes Talents Cirque with this show Ieto, last night's hugely entertaining offering at the Purcell Room by the London International Mime Festival. Mime theatre can be spoilt sometimes by lofty pretensions, but here all that was lofty was the eyewatering height at which Feldmann and Guichard were prepared to stand on perilous structures which they gleefully destabilised under themselves.

I whizzed back to my previous reviews of BlackSkyWhite when I got home last night to check how much I’d enjoyed them in the past, so disappointing was their offering for the London International Mime Festival, USSR Was Here. Russians have colonised mime theatre with a razor-edged passion and ingenuity in theatrecraft that usually makes any Russian company a must-see in the Mimefest.
